The control panel is the central point for all automatic controls and
wiring points. This panel is made, so that repair person can easily
remove it from control box, for easier service.
Following is a listing of parts and their descriptions, as found on
this panel:
A) Engine Monitor:
(8) Annunciations consisting of:
High Temperature LED:
This is a sensor that will shut gen-set
down, if certain engine temp-limits are exceeded. At this high
temp point, LED lights, until high temp is reduced.
Over Crank:
Engine will crank for 10 seconds, rest for 10 seconds,
and continue for a total of (3) cycle cranks, before shutdown and
over crank LED turns on.
Over Speed:
If speed of gen-set exceeds 300 VAC (69 HZ), the
gen-set shuts down and over speed LED will constantly flash while
engine is cranking, and when over speed fault occurs.
Engine Running:
Engine is running normally and system is func-
tioning as it should. LED light will constantly flash during cranking
and remain steady while engine is running.
Under Speed/Fail:
If engine should reduce in speed below 53 HZ,
the system will shut down and LED turns on.
Low Oil:
If engine oil pressure becomes too low, the engine will
shutdown and LED light turns on.
Not in Standby:
When mode selector switch is in the “Test” posi-
tion, the “Not in Standby” LED remains on, to remind operator that
gen-set is not in “Standby” position. When the setup and testing
procedures are finished, remember to place mode switch in
“Standby” position.
Low Battery:
If 12 VDC starting battery drops below 11 VDC, LED
turns on and remains until battery voltage is corrected.
B) Mode Selector Switch:
Control switch for manual testing and
standby (auto) position. After each fault condition happens and
fault is repaired, mode switch must be placed in “OFF/RESET”
position for 15 seconds, to reset the microprocessor control board,
before returning to normal operation.
C) Hour Meter:
Total hours of use and is used as service reminder.
D) Main Line Circuit Breaker:
UL-146 circuit breaker will trip
open upon short circuits, or overloads.
KNOW YOUR SYSTEM CONTROL PANEL
Compare the illustration with actual GILLETTE home generator system.
1) 8 Point, LED diagnostic display panel.
2) #S-2 optional alarm system interface for fault detection.
3) TS1: Electrician’s connection terminals for 2-Point Remote
Start/Stop Dry Contact Terminals.
4) TS2: Electrician’s 120 VAC Utility Power connection terminals
for powering optional equipment i.e. battery charger, oil heater,
battery blanket, etc…
TS3: Electrician’s connection terminals for 120/240 VAC
Generator Output Power.
5) Dotted line indicates cover shield protecting unauthorized per-
son’s from entering high voltage area. Licensed electrician is
required to remove hex head bolt (5), slide dotted line panel down
by approx. 2” and pull straight out, for full wiring access. Note: 10
amp fuse is removed from fuse holder and taped to upper part of
panel #3 for electricians installation
