PRE-OPERATIONAL SYSTEM

CALIBRATION

When transmitter installation and electrical connections to a suitable receiver with indicating meter are complete, and power is turned "ON", the tank level indicating system must be calibrated. Thls consists of adjusting the TU clrcutt for a full scale meter reading, which is equivalent to full travel of the float on the transmitter. See receiver instructions for caObratlon procedure.

OPERATION

Once the system has been calibrated, and power is "ON", operation of the Gems 36000 Series transmitter is completely automatic.

MAINTENANCE

An occasional cleaning of transmitters, when excessiye foreign material is present in the liquid, is done by moving floats up and down and wiping units clean durlng normal tank servicing. Zener Barriers should be checked periodically to make sure that Barrier units are clean and free from contaminating atmospheres, and are in good physical and electrical condition.

TROUBLE-SHOOTING

CAUTION

Be sure power fs "OFF" when disconnecting or connecting any system wiring.

GEMS 36000 SERIES TRANSMITTERS

A system within a tank may include one or several transmitter units, and will have a total resistance value between 1000 and 2500 ohms, as measured between the red Wire (cable pin A) and the black wire (cable pin 6). This resistance value is a constant and should not vary when unit floats are raised and lowered. If the system is malfunctioning or inoperative, disconnect receiver cable and make these three basic reststance tests on the transmitter:

1. Measure resistance from red to black wires. Refer to l.D. tag attached to transmitter for proper resistance values for that particular system (see Fig. 17). This resistance should not change when float(s) are moved up and down. If it does change, see "Corrective Ac!lon".

2. Measure resistance between black wire (cable pin 8) and whtte wire (cable pin C). This resistance should be approximately 300 ohms ± 10% with all floats at bottom rest position. and should

Increase gradually as float(s) are raise~. Note: Slight increases and decreases fn resistance will occur as floats are moved and this is normal.

When float(s) are at top positions, this resistance should equal the total "red-to-black" resistance plus 330 ohms, :t10%. If not, see "Corrective Action" below.

3. If "opens" are detected, check all cables and mating of all connectors. If open drcuits are detected within transmitter unit(s). see "Corrective Action" below.

Re-connect receiver cable to transmitter after tests have been completed.

GEMS ZENER BARRIER SAFE-PAK

See "TESTING INSTALLED BARRIER SAFE-PAK" in Zener Barrier SAFE-PAK, PIN 43540 Instruction bulletin for trouble-shooting proce· dures. These procedures must be strictly followed in order to preserve the Intrinsic safety of the system. Zener Barrier units are not repairable, and if found faulty as a result of these tests, they must be replaced.

WARNING

The pressure limitations shown in the individual catalogs and drawings for the specified tank level fndfcator involved must not be exceeded. These pressures must take into consideration possible system surge pressures and their frequencies.

For hazardous area application, such as, but not limited to, ignitable mixtures, combustible dust and flammables, the use of an ap· proved intrinsically safe device is strongry recommended. Consult factory.

The liquids used must be compatible with the materials of construction. Specifications of materials will be given on request.

For spedalized applications, consult factory.

The tank level indicator system has been des1gr:ied to be shock and vibration-resistant. However, shock and vibration should be minimized. Consult factory for assistance.

Excessive contaminants in the flulds may inhibit float operation.

Consult factory for assistance.

The tank level indicators are custom-designed for particular applications. Any change in the application of the unit, the factory must be consufled.

Elastomer seals in the sensor and cable are subject to deterioration and aging and therefore need to be checked regularly. Their life expectancy varies with the application.

Trouble-shooting and maintenance of the tank level indicator system must be in strict compliance with the procedure set forth in the trouble-shooting and maintenance section of the technical brochures. installation, operation and maintenance bulletins.

Transmitters and cables must not be field-repaired. All other field repafrs must be performed by qualified personnel only.

Tank Level Indicating Cable Assemblies

Type FSS-2

Gems cable assemblies provide liquid-tight connections at pressures from 0 to 2000 psi. They mate with 4-pin transmitter plugs to provide 0-ring-sealed electrical connections. All cable models set screw-lock securely to transmitters. (See next page for some typical in-tank arrangements.)

Important: Read the following instructions completely before installing Gems FSS-2 Cable Assemblies. Product must be used and maintained in strict accordance with Gems technical brochure and instruction bulletin. Failure to observe this warning could result in serious injuries or damages.

CAUTION! Inspect the transmitter mating surface for nicks, scratches or other imperfections which may damage the 0-rlng in the cable assembly. If any are found, they must be corrected prior to connection of the cable.

CAUTION! Do not tighten cable head nutsf

Installation Instructions •••

1. Using your fingers or a pair of needle-nose pliers, carefully pull the 4-pin plug (Gems PIN 36468) from the end of the transmitter and inspect for contamination, bent pins or dam aged insulation of the lead wires. Correct any deficiencies as required, prior to connection to the cable head.

2 . Inspect the cable head for contamination and the presence of an 0-ring. If the cable is used (or has been on the shelf for more than 12 months) the 0-ring (Gems P/N 28028) should be replaced. Also, check to be sure the 3 set screws are not protruding from the inside surface of the cable head. This will cause damage to the transmitter mating surface and might allow liquid to leak Into the transmitter tubing.

3. Generously lubricate the 0-ring and mating transmitter sur face with an 0-ring lubricant suitable for synthetic rubber 0-rings. Note: Avoid getting any lubricant In the electrical connectors.

4. Insert the transmitter plug into the mating receptacle of the cable, aligning plug key with receptacle keyway. Note: Do not force the connectors together. Make sure the trans mitter plug fits snugly and is seated on the cable receptacle.

5. Carefully guide the plug lead wires into the transmitter, as you place the cable end on the transmitter. Watch to make sure there are no pinched wires.

6 . Orient the cable in the direction of the cable clamps to avoid tight bends and firmly push the cable head onto the transmitter until It seats firmly. There is a painted black groove on all transmitters which should be covered when the cable head is seated. This groove/black line is located 3/4" from the end of the transmitter tubing.
