(dry-well recovery timer)
#RU- Number of Restarts After
Undercurrent
ADDR- RS485 Address
#RF-Number of Restarts After All Faults
Except Undercurrent
UCTD- Undercurrent Trip Delay
GF- Ground Fault Current Threshold
NOTES: SymCom's Overload Relay can be preprogrammed prior to installation by applying 120VAC
between the L1 and L2 terminals (except 575 Volt model). Power applied must be 110VAC or greater.
* 575 Volt model.
** If J Prefix is displayed in trip class setting, jam protection is enabled.
*** If "oc" is displayed in the #RF setting, then overcurrent will be included as a normal fault and the
relay will automatically restart after RD2 expires, otherwise, manual reset is required after an
overcurrent fault.
