If the SymCom Power distribution unit display alternates “LPr”1 with “RUN”, the overload relay has tripped on low power (LPr) and is timing down RD3 before restarting. To correct this issue, check programmed limits by turning the MODE SELECT knob and return the LPr setpoint to “30” to stop the low power fault.
What to do if the SymCom Power distribution unit display is showing a solid “ub”, or “oc.”?
If the SymCom Power distribution unit display is showing a solid “ub”, or “oc.”, correct the problem by checking programmed limits by turning the MODE SELECT knob. Return the OC and/or CUB setpoints to original setting listed in the programming section.
What to do if the SymCom Power distribution unit display is showing a solid “uc.”?
If the SymCom Power distribution unit display is showing a solid “uc.”, correct the problem by checking programmed limits by turning the MODE SELECT knob. Return the UC setpoint to “35” in order to stop the undercurrent fault from occurring.
