Troubleshooting procedures of power relay
1. Remove the relay from the relay socket.
2. Turn the digital multimeter to 200
Ω
of
Ω
position.
3. Connect the red probe of DMM to the relay terminal "86", while the black probe to terminal "85", the
value displayed on DMM shall be around "330
Ω
" thereby.
4. Turn the digital multimeter to 200
Ω
of
Ω
position.
5. Connect the one probe of DMM to the relay terminal "30", while the other to terminal "87", the value
displayed on DMM shall be "1" thereby;
6. Apply +24V external power (+) to the terminal "86" of relay, while (-) to terminal "85"; on the other
hand, connect one probe of DMM to the terminal "30" of relay, the other probe to terminal "87",
thereby, the DMM displayed value shall be "0".
After completing the above steps, if the values displayed on DMM conform to that described in the steps,
the relay is in good service condition.
The above steps are inapplicable to the operating contacts where the abrasion is very severe.
