About this file
This pre-solicitation synopsis is for an optimized remediation contract to conduct environmental remediation activities at multiple military installations in South Carolina and North Carolina. The contract will have a period of performance of ten years and is set aside for small businesses only. The scope of work includes maintenance of established remedies, optimization at applicable sites, and achievement of site-specific objectives at fifty-four Installation Restoration Program sites and eleven Military Munitions Response Program sites. The solicitation will be issued electronically on or around January 31, 2023, with proposals due on the date specified in the solicitation. The acquisition will be conducted using FAR Part 15 with a best value tradeoff between technical approach, past performance, and price factors.

Bldg. 543 East and West
2014‐09 Installed TIMEMARK MODEL 269R power monitor in control panel for Bldg 532, Bldg 543 East and West systems. The power monitor output contact is wired into the control circuit for the panels. When the power monitor senses over or under voltage or loss of a power phase the output contact will open and cause the panel to shut down. When power is restored or is again within the normal range the output contact will close after an adjustable time delay. The panel control circuit is energized and the system restarts. Adjustments for under/over voltage and restart time delay are provided on the power monitor. Refer to Installation instructions for TIMEMARK MODEL 269R to adjust the settings.
Restart based on the power monitor is the same in either Hand/manual or Auto. When in Hand/manual the only protection function is the motor overload or the power monitor. No other interlocks will shut the system down. If in Hand/manual and the power monitor trips, as soon as it resets the motor will restart in manual/hand mode. Hand/manual should only be used for a maintenance function when an operator is at the panel. System should NEVER be left in Hand when not attended.
DESCRIPTION
The Model 269 Over & Under 3-Phase Monitor continu-ously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal. This device features a solid-state voltage and phase angle sensing circuit, which drives a SPDT output relay.
The Model 269 is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay remains energized. When a fault condition is sensed, the output relay drops out.
The Model 269 does not require a neutral connection, and can be used on Wye or Delta systems. Each of the four voltage versions can be adjusted over a wide range. An adjustable trip delay (1-10 seconds) prevents nuisance tripping. OVER and UNDER voltage failure indicators aid in calibration and system troubleshooting.

INSTALLATION
Connect 3-phase wiring to the terminals marked A, B and C.
Connect the control wires to the terminals with the relay contact markings. The markings shown are in a TRIPPED condition.
Apply power. If the indicator lights are ON, and the contacts do not transfer when power is applied, check that all three phases are present and of the correct voltage. If all phases are correct, rotate the UNDER VOLTS adjustment fully counter-clockwise, and the OVER VOLTS adjustment fully clockwise.
If the contacts still do not transfer, remove power from the unit, and reverse two of the three input wires. Re-apply power.
The contacts should then transfer (LED-off).
ADJUSTMENT
Turn the DELAY SECONDS trip delay adjustment counter-clockwise.
Rotate the UNDER VOLTS adjustment slowly clockwise until the contacts transfer to a tripped condition (LED-on).
Slowly turn the UNDER VOLTS adjustment back counter-clockwise until the contacts reset to the normal condition (LED-off).
Rotate the OVER VOLTS adjustment counter-clockwise until the contacts trip (LED-on).
Slowly turn the OVER VOLTS adjustment back clockwise until the contacts reset to the normal condition (LED-off).
These settings will be correct for most installations.
MODEL 269 Over & Under 3-Phase Monitor
READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.
KEEP THIS DATA SHEET FOR FUTURE REFERENCE.
GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 269 .
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions Set the SECONDS delay adjustment to the desired amount of trip delay. This delay will help prevent nuisance tripping.
Should nuisance tripping still occur, turn the OVER VOLTS, and UNDER VOLTS adjustments slightly farther.
NOTE: In eliminating nuisance tripping, the voltage ad-justments should be rotated in very small increments, until the true nuisance trips no longer occur.
TROUBLESHOOTING
Should the Model 269 fail to operate properly, check that all three voltages are present, and are of the correct level.
Check all fuses, and verify that all wiring connections are correct. Should problems persist, contact your local Time Mark Distributor, or the factory for further assistance.
WARRANTY
This product is warranted to be free from defects in materials and workmanship, and is covered by our exclusive 5-year Unconditional Warranty. Should this device fail to operate for any reason, we will repair it for five years from the date of manufacture. For complete warranty details, see the Terms and Conditions of Sales page in the front section of the Time Mark catalog or contact Time Mark at 1-800-862-2875.
