Chapter 3 Maintenance and Troubleshooting
This chapter describes the transfer switch installation, commissioning and common faults and maintenance methods.
3.1 Start Up / Function Test
1. To Test Manual Operation
Two power supply Sources must be disconnected before manual testing can begin. Refer to chapter 2.2.1 to run
Manual Operation mode. Operate the transfer switch from I position to II position and turn back to I position with
handle. The operation should be smooth, without interruption. If so, switch is operating correctly in manual mode.
2. To Verify Voltage Detection
First make sure the rated voltage of the transfer switch on the nameplate is the same as the dual-power supply
rated voltages. Next, review the C2000 or the C1000 controller, to make sure the power is being supplied to
transfer switch. Source I and Source II Auxiliary Indication LED lights are on (green), This should indicate your
wiring is correct.
If using the C2000 controller, Double-check and measure the dual-supply voltage, to make sure voltages are
consistent to what is indicated on the C2000 controller .
DANGER
!
When measuring Voltage, pay attention to not touch the terminals and copper bars, otherwise it could result in death, or serious
injury.
