(FC_1) LOW BATTERY VOLTAGE
If the generator cannot start because the battery output
power is below that needed to crank the engine, the digital
display will show
FC_1 and the remote LED will repeatedly
flash once with a pause.
A completely discharged battery will not be capable of
powering the digital display. The causes for a low or
discharged battery may be:
• Blown fuse in the transfer switch
• Blown fuse in the generator control panel
• Failed battery
• Parasitic drain on the battery
• Failed trickle charger
The circuit functions and test/repair procedures for these
conditions are outlined below.
The trickle charge circuit is a float-type charger. When utility
voltage is present and the unit is switched to the
AUTO or
OFF position, the trickle charge circuit in the control panel
will maintain the voltage of a fully charged battery.
TEST 1 - Check Battery
1. Set control panel system switch to OFF .
2. Remove the 15 Amp fuse.
3. Disconnect the negative (
- ) battery cable.
4. Disconnect the positive ( + ) battery cable.
5. Using the approved procedure for your battery tester,
check the battery state-of-charge.
• If the battery is discharged, connect to an
appropriate battery charger. Set the charger at 2
Amps until a full charge is indicated. DO NOT
exceed the 2 Amp charge rate.
• If battery replacement is required, the
replacement must be a12VDC, AGM type battery.
Refer to the Installation Manual for complete
battery information.
• Once battery state of charge is satisfactory,
proceed to TEST 2 - Check Trickle Charge
Voltage at Battery.
NOTICE: DO NOT replace with a liquid electrolyte (lead-acid)
type battery.
TEST 2 - Check Trickle Charge Voltage at
Battery
1. Set control panel system switch to OFF .
2. Remove the 15 Amp fuse.
3. Inspect the fuse to see if blown.
• If fuse is good, proceed to Step 4 .
• A blown fuse indicates a short in the circuit.
Repair any short and replace fuse before
proceeding to
Step 4 .
4. Disconnect the negative ( - ) battery cable. Leave
positive ( + ) battery cable connected to the battery.
5. Set the meter to measure DC voltage. Connect
positive ( + ) meter test lead to positive ( + ) battery
terminal.
6. Connect negative ( - ) meter test lead to negative ( - )
battery terminal.
• If approximately 12.5 VDC is measured, proceed
to Step 7 .
• If battery voltage is low, recharge or replace
battery as necessary, than proceed to Step 7 .
7. Disconnect negative ( - ) meter test lead from negative
( - ) battery terminal and connect to negative ( - )
battery cable.
8. Reinstall 15 Amp fuse.
9. Ensure utility voltage is turned
ON .
10. Set control panel system switch to ON .
NOTICE: The control panel must be connected to a 12 volt
battery to turn on internal circuits. Once the trickle charge
circuit is turned on, the battery can be disconnected and
battery charge output will remain.
11. While observing the meter and keeping the negative
( - ) meter test lead connected to the negative ( - )
battery cable, momentarily touch the battery cable
and meter test lead to the negative (
- ) battery
terminal ( A , Figure 7) for 30 seconds, then remove
( B , Figure 8). This will turn on the trickle charger
long enough to read the trickle charge output voltage
on the meter. Approximately 13.5 VDC should be
measured.
