Checks with the Unit Powered Off
Perform the following checks with the unit powered off.
1. Ensure the power to the unit is off
2. Check for visible damage to the unit, cables, and connectors.
3. Ensure all unit connectors are installed correctly and are fastened tightly.
4. Check to determine whether any system-related circuit breakers have been
tripped.
5. Ensure all phases of the main input power are applied to the appropriate power
supply terminals.
6. Ensure there is input power to both the unit and the remote, and ensure the input
power meets specifications.
7. Ensure ground connections are adequate and secure and comply with local safety
codes.
8. Check the position of the switches on the DIP for the serial (Host) port (if your
unit has a Host port) against the addressing information in the “I/O
Communication and Control”chapter.
9. Ensure that the interlock loop is closed both at the Contactor Interlock and at the
User port. (See the description of the Contactor Interlock in the
“Installation”chapter for more information.)
10. Ensure that input power meets specifications. (See the “Specifications” chapter
for more information.)
Checks with the Unit Powered On
1. Check the unit’s input and remote power connections to ensure the proper power
is being supplied to the unit.
2. Check the LEDs on all units to determine that the proper ones are lit.
3. Note any error code (that is, any “Exxx”number) displayed on the front panel or
Pinnacle Remote Active Panel. See “Error Code Troubleshooting Table” later in
this chapter for additional information.
4. Working with the passive front panel, ensure that the front panel LEDs POWER
ON, INTERLOCK, OUTPUT, and SETPOINT LEDs are lit (see
“Troubleshooting Table” in this chapter). Note which, if any, of these are not lit.
If the INTERLOCK LED is not lit, error code E020, E022, or E023 should be
displayed on the front panel. See “Error Code Troubleshooting Table” in this
chapter for a suggested response to any of these errors.
5. Verify that LEDs light to show the control and regulation settings. Then verify
that the OFF LED is lit.
