4.3 Testing the Relay Module
The relay module is located on the outer electrical panel. See Section 4.1.
A green light on the relay module indicates that it is receiving power and is ready for
use. Note that the relay module requires 6-8 seconds to initialize after it receives power
(i.e., the lift is plugged in), during which time the relay light is red. Always give the
module time to initialize before performing any testing on it.
To test the function of the relay module, refer to the logic diagram on page 37.
If the relay module is not receiving power, check for and correct the following conditions
as necessary:
1. The lift is not plugged in. Plug the lift in.
2. The service outlet does not have power. Plug the lift into an outlet that does have
power.
3. The GFCI on the power cord has been tripped. Reset the GFCI.
4. The power supply is not supplying 12 VDC. Refer to Section 4.4 to check it.
5. There has been a wiring harness or connector failure. See the Electrical Diagram on
page 37 to continue troubleshooting, or contact Ascension.
