(Only if the breaker has manual trip function). Verify that DC voltage is maintained on the output of the DC UPS. Following the test, reset the AC circuit breaker for the DC power supply and verify the DC voltage is present on the output of the DC UPS. w. If panel is equipped with DC fuses for auxiliary devices (not fuses associated with input/output (1/0) loops), close each fused disconnect terminal block one- at-a-time. Verify that the correct DC voltage is present at each of the devices served by these fuses. x. If panel is equipped with DC fuses for 1/0 loops, close each fused disconnect terminal block one-at-a-time. Verify that the correct DC voltage is present at each of the 1/0 served by these fuses. y. Verify each DC fuse de-energizes and energizes each of the devices or 1/0 points served by these fuses. z. Disconnect AC power from the panel without opening the AC main circuit breaker or AC main fused disconnect terminal block. Verify that DC voltage on the output of the DC UPS is maintained for at least 10 minutes. Following the test, reapply AC power to panel, verify the UPS is charging the battery backup. 4. 1/0 Checkout The Contractor shall verify every 1/0 point operates correctly, including ones marked as spare by completing the following: a. Configure the PLC for 1/0 checkout (PLC program, networking configured, etc.). b. Test digital inputs by applying the appropriate voltage or by applying a jumper to the field terminals and checking the status lights on the input module and appropriate tag in the controller. c. Test the digital outputs by forcing the output in the Controller and checking the status light on the output module and that the correct voltage or contact state is present at the field terminals. d. Test analog inputs by applying 3.8mA, 4mA, 12mA, 20mA, and 20.2mA to the filed terminals and checking that the tag in the Controller varies accordingly. e. Test analog outputs by forcing the output in the Controller to values between the minimum and the maximum and checking that the current at the field terminals varies accordingly. f. If the panel is equipped with any indicating lights or process displays, verify they operate correctly. The Contractor shall utilize the form in Exhibit C or an equivalent approved equal to complete the FAT. Upon completion of the witnessed FAT with a City Representative, the Contractor shall provide a UL508 certification label and supporting documentation confirming and validating proper operation of the equipment as well as conformance with quality, configuration, and testing standards. 3.
