The steps below provide further details to check and verify proper operation of the Digital Relay
Outputs on MAXIM Series controllers, as illustrated in Figure 5-3 on the previous page.
1. Verify that the MAXIM controller on which the Digital Relay Outputs will be checked is powered
OFF. You must also verify that power is turned OFF to all of the digital output circuits to be
checked.
2. Beginning at the first device connected to the NO contacts, turn the power ON to the output
device.
3. Visually check to verify that devices connected between the NO and Com terminals are OFF.
If this cannot be verified by a simple visual observation, connect a DMM across the device to
measure the voltage. With the DMM set to the appropriate voltage, verify the that the measured
voltage reads 0V.
4. Verify that the device is OFF by either visual inspection of the device itself, or verifying that the
measured reading on the DMM is 0V.
5. Temporarily connect a jumper wire between the NO and Com contacts of the Digital Relay
Output to be checked. Verify that the jumper wire is of adequate size to temporarily carry the
load.
6. Now turn the power ON to the output device.
7. Verify that the device is ON by either visual inspection of the device itself, or verifying that the
measured reading on the DMM is the expected operating voltage of the device.
8. Turn the power to the output device OFF.
9. Remove the jumper wire connected in Step 6.
10. Repeat Step 2 through Step 10 for the remaining output devices connected to the NO contacts.
