NOTICE
Contact S&C Electric Company to conduct calibration verification and operational
testing services.
WARNING
The following procedures require the PureWave UPS System to have utility power. The
system should be placed in the
Bypass Isolate state before conducting the proceeding
equipment testing procedures.
Conduct the following equipment testing procedures:
¨
Verify all smoke detectors are available, undamaged, and operate when tested.
¨
Enable the system and verify the air conditioners are working properly by measuring
and recording the compressor current draw on each A/C unit with an ammeter after the
A/C unit is running for 2 minutes. Operate the A/C unit by installing switchable output
blocks in DO00 (EA10 position S8) and DO01 (EA10 position S9) and turn on. The current
should be between 10 and 15 amps. Record these measurements in Table 8 below.
¨
Hold your hand under each of the air conditioners to verify cool air is still being produced
¨
Record the ambient temperature when air conditioner testing is being performed.
Replace the switchable output blocks with the original output blocks after verification
(if used).
Ambient Temperature: _________________
¨
To verify the heaters are working properly, check each heater to verify they are still
putting out heat. Operate the heaters by installing a switchable output block in DO11
(EA11 position S11) and turn on. Replace the switchable output block with the original
output block after verification.
¨
Verify the container temperature sensing via monitoring computer.
¨
Remove a thermocouple from the analog board and verify there is a broken thermocouple
warning on the HMI and on the LCD.
¨
Verify (visually) the control relays are not damaged.
¨
Verify all fuses are in working order on the control panel.
¨
Verify the service outlets and lights are operational.
