Issue 5 – ETA-ECS6RM Channel Activation Status LED is Flashing Green and AC Power and Active LED at the ECM Module is
Illuminated.
Possible Cause
The AC Mains Voltage at the ECM Module reached between 127VAC-132VAC or the voltage dropped
between 101VAC- 107VAC.
between 101VAC- 107VAC.
Action Needed
The ETA-ECS6RM must be re-sequenced to turn off the LED. Measure the AC Mains before the ECM
Module. If the voltage is between 117VAC and 123VAC you may proceed to reset the ETA- ECS6 by
restarting the start up sequence.
Note: It is important to have all equipment that was connected to that AC Mains Line be inspected for
proper operation. If the problem persists, contact your local power company for the cause of unstable AC
line conditions.

Issue 6 – No Voltage Reading at the ETA-ECS6RM
Possible Cause #1
Check Issues 1 - 4 first.
Possible Cause #2
Proper Channel is not selected for viewing.
Possible Cause #3
Channel Activation LED is Illuminated Green but the Voltage display is not on. Check the wiring between
the ETA-ECS6RM Channel and the ECM module. “V”, “A” and “D” must be in the correct polarity.

Issue 7 – No Current Reading at the ETA-ECS6RM, Meter Reads ‘nA’
Possible Cause #1
An ETA-ECM20 Module is connected. This module does not support current read out.
Possible Cause #2
Check Issues 1 - 4 first.
Possible Cause #3
Current Draw of ECM Module must exceed 500mA to register.
Possible Cause #4
Proper Channel is not selected for viewing.
Possible Cause #5
Channel Activation LED is Illuminated Green but the Current display reads “nA”. Check the wiring between
the ETA-ECS6RM Channel and the ECM module. “V”, “A” and “D” must be in the correct polarity.

Issue 8 – Not All Channel Status are Illuminated Red or Green
Probable Cause
No ECM Module connected to the ETA-ECS6RM. Note: For any of the 6 Channel Status LEDs to illuminate
a ECM Module must be connected to the ETA-ECS6RM. It ok to use only some of the six channels and not
have all channels illuminated.

have all channels illuminated.
Issue 9 – Sequence Timing or Slave / Master Unit Dip Switches Has Been Adjusted but No Effect Has Taken.
Probable Cause
After changing of the DIP switches you must cycle the ETA-ECS6RM for the settings to take effect.
Issue 10 – Current Meter Reads “nA” on A Selected Channel but the Channels is Functioning.
Probable Cause #1
ETA-ECM20 module connected. Only ETA-ECM20M, ETA-15SH and ETA-20SH modules support the current
read out circuitry.
read out circuitry.
Probable Cause #2
The “A” terminal wire is not connected.
Probable Cause #3
The correct module type is connected, but there is not enough current being drawn to register. Note: It
takes .7A for current draw from the ECM module for a reading.
takes .7A for current draw from the ECM module for a reading.
Issue 11 – No LEDs are illuminated on the ETA-ECS6RM and the Voltage display reads "nC".
Probable Cause
No ECM modules are connected to the ETA-ECS6RM or the ECM modules have no AC power to them.
