UP and DOWN Contact Inputs
Remote set point adjustment may be accomplished
by connecting a SPDT momentary contact switch
to the J1 connector UP and DOWN contacts. To
connect this switch, the common terminal must be
connected to J1-4 (CGND). The other two switch ter -
minals are connected to J1-2 (UP) and J1-3 (DOWN).
Refer to Section 4 – Features and Protection for a
detailed description of the UP and DOWN contact
function.
Parallel Generator Compensation Enable/Disable
(DROOP OFF)
A user can enable or disable the integrated load
sharing function of the regulator by opening or
closing contact between J1-10 (DROOP OFF) and
J1-4 (CGND). Closing the contact disables the droop
function. Refer to Section 4 – Features and Protection
for a detailed description of the Load Sharing
function.
Excitation Enable/Disable (EXCITATION OFF)
A user can enable or disable excitation by opening
or closing contact between J1-11 (EXCITATION OFF)
and J1-4 (CGND). Closing the contact disables exci -
tation. Refer to Section 4 – Features and Protection
for a detailed description of the Excitation Off
function.
Auxiliary Input (AUX_IN (+), AUX_IN (-), and AUX_
LOOP)
This input allows a user to control the regulator with
an auxiliary piece of equipment by connecting a
voltage source to J1-1 (AUX IN +) and J1-12 (AUX IN
-). The regulator can also be configured to accept a
voltage or current to be metered on this input. Refer
to Section 4 – Features and Protection for a detailed
description of the Auxiliary input function.
VAR/PF Enable/Disable (VAR/PF_OFF) (EC+ only)
A user can enable or disable the VAR or PF regula-
tion modes by opening or closing contact between
J1-9 (VAR/PF_ON) and J1-4 (CGND). Opening the
contact enables VAR/PF regulation if the regula -
tion mode was set to VAR or PF in the HMI or
DVRPortal™. Refer to Section 4 – Features and
Protection for a detailed description of the VAR/PF
regulation function.
Note: Operation in VAR or PF modes should only
be enabled when the generator is paralleled with
utility (infinite bus). If the VAR/PF_OFF is open
during power up of the regulator in VAR or PF reg-
ulation modes, a Generator Start Up Fault occurs.
