Current Verification
If it is necessary to verify the current flow through the EPS system, it can be checked with a digital DC
ammeter set on the Milliampere scale. The correct electrical currents for nominal system capacities
are listed in Figure 22.
Nominal System Capacity, Tons
Current Rating
1.5 thru 2.5
80 mA +/- 10%
3.0 thru 3.5
120 mA +/- 10%
4.0 thru 6.0
240 mA +/- 10%
Figure 22. EPS Current Ratings
To check the current, disconnect the
“Loop”
wire from the EPS module as shown in Figure 23 and
connect the DC ammeter as shown to measure and verify the current flow.
Figure 23. Test for DC Current
WARNING!
Use extreme caution when checking current through the EPS system. Turn
OFF the main disconnect to the compressor unit when setting up the Ammeter
for the current measurement. Turn the power supply on only after the
Ammeter is in place for the measurement and hands and body are clear of all
electrical circuit conductors. Turn OFF the main disconnect after the current
measurement has been taken and before attempting to disengage the Ammeter
and re-connect the EPS wiring. Failure to do this, could cause personal injury
or death.
