11 Startup
Apply the rated control supply voltage at terminal blocks A1/
A2. The PWR LED and K1 LED light up.
Enabling current path 13/14 closes, and confirmation cur-
rent path 21/22 opens.
12 Proof test
In the proof test, you check the individual relay channels.
1. Activate A1/A2.
2. Apply the 24VDC diagnosis power supply to con-
tact21.

If the green DGN-LED lights up, the module is functional.
(Apply 24VDC to signal output M1.)

If the red ERR LED lights up, replace the module.
(Apply 0VDC to signal output M1. Error acknowledgment
via A1 is inactive.)

If the diagnostic voltage supply is present and the green
DGN LED and the red ERR LED are on, replace the module.

If the diagnostic voltage supply is present but neither of the
LEDs specified is on, replace the module.
For compliance with UL approval, use copper
wire that is approvedupto 60°C/75°C.
