SECTION 2.0 – INSTALLATION

Section 2.1 – Pre-Installation Checks

2.1.1 Upon receipt of equipment, inspect all components for obvious signs of physical damage. Report any/all damage to the carrier that delivered the equipment and notify Hellan Strainer - call 888-4HELLAN (888-443-5526) and ask for customer service.

2.1.2 Remove any foreign material in the inlet and outlet openings of the strainer before installation.

2.1.3 Check nameplate attached to strainer body to determine the size, type, and screen perforations. All data on this nameplate should be included in any future inquiry concerning this strainer.

Section 2.2 – Strainer Orientation

2.2.1 The DA style Hellan Strainer is an in-line strainer and does not require mounting brackets. However, proper pipe support must be provided on both sides of the strainer in accordance with all local plumbing codes.

2.2.2 The strainer casting includes a flow arrow showing the direction of flow through the strainer. As a cross reference, the strainer screens/motors are oriented in a ‘V’ configuration where the tip of the ‘V’ is the discharge side of the strainer.

Please reference the cutaway diagram in section 3.1 (below)

2.2.3 The DA style Hellan Strainer must be installed in one of two proper orientations.

2.2.3.1 The PREFERRED orientation is in the vertical position where the influent flow enters at the bottom of the strainer and the effluent discharges from the top.

2.2.3.2 The ALTERNATE orientation is to mount the strainer in a horizontal position. When the strainer is installed in this orientation it is important to position the drain connection facing downward.

Section 2.3 – Drain/Flush Line

2.3.1 The drain line must be installed in a downward position to allow gravity to aid the removal of solids.

2.3.2 It is not recommended to install the drain line in an upward direction as this may result in problems with solids clogging the drain line.

5 | P a g e

Section 2.4 – Electrical

2.4.1 Motor Rotation

The screen motors must be wired so that the screens rotate in the proper direction. It is important to ensure that the solids are removed from the screens during the cleaning cycle. Check the rotation of the screen motors. The proper rotation is as follows:

2.4.1.1 The screen shaft spins clockwise when viewed from the shaft end of the screen.

2.4.1.2 The motor spins clockwise when viewed from the fan end of the TEFC motor.

7 | P a g e

Section 3.1 - General Overview (continued) The Hellan Strainer supplied for this project is an automatic, in-line, self cleaning, dual screen strainer designed to remove particles larger than 1/8”. The strainer functions by passing the solids-laden flow across the strainer screens (2) utilizing the outer surface of the screens to remove all solids larger than 1/8” (nominal). The housing is made of cast steel and the screens are fabricated of perforated stainless steel for both corrosion resistance and durability.

As solids collect on the outer surface of the screens the pressure will increase and the flow decreases. To maintain consistent performance (i.e., design flow) it is necessary to periodically remove the solids from the strainer. A differential pressure switch should be installed to automatically monitor the differential pressure across the screens (i.e., across the inlet/outlet). When the differential pressure reaches a predetermined value (factory set at ~4 psi), the strainer will initiate an automatic cleaning/flush cycle.

If a DP switch is installed, when the DP switch calls for a cleaning cycle, both screen motors will be energized for a set time period (factory set at 15 seconds). The motors rotate the screens several complete rotations via a motorized worm-gear reducer (100:1). Internal scraper bars located adjacent to the screens are included to facilitate removal of solids from the screen surface. As the screens rotate the scraper bars remove the solids from the surface of the screens.

Simultaneous to energizing the screen motors, a flush valve is energized (opened) to divert the solids laden flow to an acceptable location. Opening the flush valve creates sufficient fluid turbulence within the strainer to keep the solids from re-depositing on the screen surface. The solids are removed from the strainer by diverting a portion of the flow to the flush line.

The flush cycle is only active for a short duration (~15 seconds). During this time approximately 5% of the influent flow is diverted to the drain line. However, because the duration of the flush cycle is short, the actual volume of fluid sent to the drain line is very small.

The frequency of the flush cycle is determined by the solids load entering the strainer.

This will vary seasonally and also with environmental conditions such as heavy storms or algae blooms.

8 | P a g e

Section 3.1 - General Overview (continued) The PLC program also includes a default timer that will initiate a flush cycle automatically if a high differential pressure is not detected within a set time period. The default timer is factory set at 24 hours.

NOTE: Factory timer settings can be field adjusted (see section 3.3 – 3.5).

In addition to automatic operation, the ECP includes a push button for manual activation of a cleaning cycle (‘CYCLE START’).

Upon completion of the cleaning cycle the screen drive motors and flush valve are de-energized and all timer values are automatically reset for the next cleaning cycle.

Section 3.2 – Cleaning Cycle Details for Automatic Strainers As solids collect on the outer surface of the screens the differential pressure across the screens will increase and the flow decreases. To maintain consistent performance (i.e., design flow) it is necessary to periodically remove the solids from the strainer.

A differential pressure switch will automatically monitor the differential pressure across the screens (i.e., across the inlet/outlet). When the differential pressure reaches a predetermined value, the strainer will initiate an automatic cleaning/flush cycle.

The motors rotate the screens several complete rotations via a motorized worm-gear reducer (100:1). Internal scraper brushes located adjacent to the screens are included to facilitate removal of solids from the screen surface. As the screens rotate the scraper brush removes the solids from the surface of the screens.

Simultaneous to energizing the screen motors, a flush valve is energized (opened) to divert the solids laden flow to an acceptable location. Opening the flush valve creates sufficient fluid turbulence within the strainer to keep the solids from re-depositing on the screen surface. The solids are removed from the strainer by diverting a portion of the flow to the flush line.

The flush cycle is only active for a short duration. During this time approximately 5% of the influent flow is diverted to the drain line. However, because the duration of the flush cycle is short, the actual volume of fluid sent to the drain line is very small.

The frequency of the flush cycle can be determined by the owner evaluating the amount of the solids load entering the strainer. This will vary seasonally and also with environmental conditions such as heavy storms or algae blooms.

9 | P a g e

Upon completion of the cleaning cycle the screen drive motors and flush valve are de-energized and all timer values are automatically reset for the next cleaning cycle.

Section 3.3 – Electric Control Panel & Electric Components The control panel and motorized valve package is designed to monitor the differential pressure across the strainer inlet/outlet and to initiate/control the cleaning cycle.

3.3.1 Hand/Off/Automatic Rotary Selector Switch

This switch controls/initiates both the Flush Valve and the Screen Drive Motors.

3.3.1.1 HAND

Momentary contacts which will open the drain valve and run the screen drives. Upon release of the switch, it returns to off, the drain valve closes, and the screen drive stops.

3.3.1.2 OFF

In the OFF position, the power is interrupted to both the Flush Valve and the Screen Drive Motor. The control panel remains powered, but the cleaning operation is disabled.

NOTE: If service is to be performed on any electrical components, the main disconnect located on the control panel MUST be turned off.

3.3.1.3 AUTOMATIC

In the AUTOMATIC position the strainer cleaning cycle is automatically initiated by the differential pressure (DP) switch. When the DP exceeds the set point (factory set at 4 psi) the strainer will initiate a cleaning cycle.

The control panel will perform one cleaning cycle upon closure of an initiation switch.

There are three methods of initiating a cycle:

Differential Pressure Switch – As the screen clogs, the pressure drop will rise.

At a pre-set point, a cleaning cycle will start.

Interval Timer – The interval between cleaning cycles can be set from 0 to 99 hours 59 minutes. Factory recommended minimum is 5 minutes. The elapsed time is reset to zero if a cleaning cycle is started by any method or if the H-O-A switch is turned to off then back to automatic.

NOTE: There is a time delay before accepting the next cycle start, which allows the fluid turbulence to subside. This turbulence may otherwise cause the differential pressure switch to trigger unnecessary cleaning cycles.

10 | P a g e

Manual Cycle Start – This is a momentary push-button that will initiate a cleaning cycle.

3.3.2 Indicating Lights

Power On - Panel light is energized indicating the ECP has active power.

Cleaning Cycle in Progress- Panel indicator light energizes when a cleaning cycle is active.

High Pressure Alarm -If the strainer does not clean properly, the pressure drop will continue to build until the alarm lights. This light is energized when the pressure drop across the strainer exceeds a maximum value (factory set at 8 psi). If/when this occurs there is an unusual problem that must be corrected (see Troubleshooting; section 6.0).The alarm is self-resetting when the differential pressure drop lowers below the set point. Auxiliary contacts in the control panel can be attached to a remote alarm.

3.3.3 Enclosure Specifications

ECP Enclosure is rated NEMA 4X Pressure switch is rated NEMA 4 Flush/Drain Valve Actuator is rated NEMA 4 Screen drive motor is TEFC

3.4 Programmable Logic Controller (PLC) – Allen Bradley PICO

An Allen Bradley PICO Programmable Logic Controller (PLC) is used to control cleaning cycle parameters including all timer values. The timer values control the following parameters:

Timer Variable T-1 Controls screen cleaning time (factory set at 15 seconds) T-2 Time delay from end of cleaning cycle until all values are reset (factory set at 45 seconds) T-3 Default timer to initiate automatic cleaning cycle if high DP is not detected (factory set at 24 hours)

NOTE: T-2 is utilized as a safe-guard to prevent the strainer from back-to-back cleaning cycles. It is normal for the differential pressure to fluctuate slightly upon the completion of a cleaning cycle when the Flush/Drain Valve closes. To prevent this, the T-2 timer is used to lock-out (delay) the DP signal from controlling the cleaning cycle until this default time has expired. Upon expiration of the T-2 timer the PLC will initiate a cleaning cycle either when the DP set point is triggered or when the default timer (T-3) has timed-out.

11 | P a g e

The procedure for adjusting the timer values is as follows:

3.4.1 Press the ‘OK’ button. This brings up the next screen. The cursor should be flashing on the word ‘PROGRAM’.

3.4.2 Arrow down to ‘Parameter’ using the center rocker switch. The cursor should be flashing on the word ‘Parameter’.

3.4.3 Press the ‘OK’ button; this brings up the next screen which is a list of all adjustable timers.

3.4.4 To change T-1, first confirm that the cursor is blinking on the ‘T’ of T-1 and then press ‘OK’. This brings up a screen that lists the rungs where the timer is used.

With the cursor blinking on the first digit press ‘OK’. Then use the up/down arrows to change that digit or the right/left arrow to change other digits. When done setting values press ‘OK’.

3.4.5 Press ‘ESC’. This will bring you back to the list of adjustable timers.

3.4.6 Use the Up/Down arrows to move to the other timers and follow steps 4 & 5 (above).

3.4.7 Press ‘ESC’ two (2) times to return to the main menu.

Section 3.5 Differential Pressure Switch (Mid-West Instruments)

Front View of Differential Pressure Switch

The Differential Pressure (DP) switch includes two set points that are factory set as follows:

P1: The P1 set point is factory set at 4.0 psi. This set point automatically initiates a cleaning cycle.

P2: The P2 set point is factory set at 8.0 psi. This set point activates the ‘HIGH PRESSURE’ alarm.

12 | P a g e

3.5.1 Set Point Adjustment Procedure

The factory set points rarely need to be adjusted; however, if adjustments are necessary the procedure is as follows:

3.5.1.1 Cleaning Cycle Pressure (P1)

The cleaning cycle pressure setting is factory set at 4 psi. Should this pressure need to be changed there is an adjustment screw located on the LEFT side of the device (left side when looking at the indicating dial).See photograph below:

ADJUSTMENT INSTRUCTIONS

Differential/Pressure/Vacuum Switch

General:

1. Check proof pressure of switch on name plate or catalog. NEVER EXCEED THIS PROOF

PRESSURE.

2. Note the adjustable range of switch (increasing or decreasing pressure) as listed in the catalog or on the name plate.

3. Check the catalog listing for actuation value of the switch.

To set the switch you need: 1. A pressure/vacuum source

2. A pressure/vacuum gauge

3. An electric continuity tester

CAUTION! -ALWAYS CHANGE PRESSURE SETTING GRADUALLY.

-ALWAYS check switch setting before making any adjustments.

Step 1. Determine if the pressure/vacuum set point is on increasing or decreasing pressure.

Step 2. If the set point is on increasing pressure, then decrease the pressure/vacuum of the source starting at a point lower than the set point. Use maximum 1/4 turn on adjustment screw.

If the set point is on decreasing pressure, then increase the pressure/vacuum of the source starting at a point higher than the set point.

Step 3. Using the continuity tester and the pressure/vacuum gauge determine the actuation point of the switch.

Step 4. If the actuation point is above the desired value, turn the adjustment screw or knob per instructions in the pressure switch catalog to increase the actuation point, and if it is below, turn the adjustment screw or knob in the opposite direction to decrease it.

Step 5. For exact pressure/vacuum setting, cycle pressure/vacuum switch and make fine adjustments by repeating steps 2 through 4 (trial and error process) until the desired setting is obtained.

Note 1. For proper electrical connection follow colors of wire insulation or instructions on terminal code tag attached to switch.

Note 2. Dual control switches should be set one side at a time. Recheck both sides after final setting.

CAUTION! -DO NOT force adjustment screw when it becomes difficult to turn.
