PRELIMINARY SETUP – SAFETY
ELECTRICAL SHOCK HAZARD
Failure to follow these instructions may result in
serious personal injury, death, and/or property
damage.
Installation and repair of electrical generators
and voltage regulators should be attempted
by qualified personnel only. Electrical con-
nections shall be made by a qualified electri-
cian in accordance with all local, national,
international and/or other applicable codes,
rules or regulations and sound practices.
Do not touch electrically live parts.
Disconnect, lockout and tag prime mover
and input power supplies before installing or
servicing voltage regulator. Use a voltmeter
to verify that power is off before contacting
conductors.
Do not open terminal box or touch unpro-
tected terminals while the generator shaft
is rotating. Shaft rotation produces voltage
in generators even when no excitation is
applied. Residual voltage is present at the
generator leads and regulator connections
even when the regulator fuse is removed.
Ground (earth) generators in accordance
with local, national, international and/or other
applicable codes, rules or regulations.
Use caution when working around the
component side of the DVR
®
. Voltage levels may
be present at the exposed components when the
unit is energized. The protective cover MUST be
installed whenever the regulator is energized.
Note: Read and understand the operation of the
individual adjustments before attempting any
adjustments.
PRELIMINARY SETUP – ON GENERATOR
The DVR
®
may be configured on the generator using
the following procedure:
1. Before starting the engine, remove the regu-
lator’s 4.0 A fuse. This will prevent the gen-
erator’s PMG from energizing the regulator
and prevent unintended operating functions
from occurring.
2. Perform all preliminary engine governor
adjustments with the regulator de-energized.
3. After initial governor adjustments are com -
plete, shut down the prime mover. Reinstall
the 4.0 A fuse. Disconnect the E3 and F+
terminal connectors from the regulator and
temporarily insulate them to prevent acci-
dental shorting.
4. Start and run the generator at rated speed.
The regulator will enter a Loss of Sensing
shutdown mode, indicated by F011 on the
display.
5. At this time, initial adjustments can be
made. If adjusting via the HMI, see
Section 6 – Making Settings Changes . If
adjusting via DVRPortal™, see Section 7 .
6. After the initial adjustments are made, shut
down the generator and reconnect the regu-
lator leads removed in Step 3. The generator
may be started and final adjustments may be
performed on the regulator.
PRELIMINARY SETUP – ON BENCH
The DVR
®
may be configured on a bench using the
following procedure:
1. Connect a 100-120 Vac 50/60 Hz source to
terminals 3, 4 and GND as follows:
a. 120 V hot – terminal 3
b. 120 V neutral – terminal 4
c. 120 V ground – terminal GND
