TP-5867 11/02 29 Section 4 Controller Troubleshooting
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working
on the generator set.
Remove the negative (--) lead first
when
disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative (--) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death.
Electrocution is possible
whenever electricity is present. Open the main circuit
breakers of all power sources before servicing the equipment.
Configure the installation to electrically ground the generator
set, transfer switch, and related equipment and electrical
circuits to comply with applicable codes and standards. Never
contact electrical leads or appliances when standing in water
or on wet ground because these conditions increase the risk of
electrocution.
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage . Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
Cyclic Cranking Board Test Procedure
1. Place the generator set master switch in the OFF
position.
2. Disconnect power to the battery charger, if
equipped.
3. Disconnect the generator set engine starting
battery, negative (--) lead first.
4. Remove the generator set housing roof to gain
access to the controller.
5. Disconnect the leads connected to terminals 1, 2,
and 3 of the cyclic crank circuit board. Remove the
cyclic crank board from the controller.
See
Figure 4-2 for the location of the circuit board.
6. Connect a voltmeter across cyclic crank board
terminals 2 and 3 with the voltmeter on the
12--15 volt DC scale. See Figure 4-10.
7. Connect the positive (+) battery terminal to circuit
board terminal 2. Connect the negative (--) battery
terminal to cyclic crank terminal 1. Verify that the
voltmeter shows 12 volts DC for approximately
eight seconds (factory crank setting) and then no
voltage for approximately three seconds (factory
rest setting). This sequence should continue for
30 seconds (8 on, 3 off, 8 on, 3 off, 8 on).
Note: The cyclic crank board may have been
customer-adjusted to provide longer or
shorter crank/rest cycles.
8. Adjust the on and off times, if necessary, by turning
the adjustment potentiometers cw to increase the
time or ccw to decrease it.
9. If there is no voltage at the cyclic cranking board,
check the battery voltage and the cyclic cranking
adjustments. The cyclic crank feature does not
operate at low battery voltage or when both circuit
board potentiometers are in the full ccw position. If
there is no voltage with the battery fully charged
and the cyclic crank board correctly adjusted,
replace the cyclic crank circuit board.
10. Reinstall or install the new cyclic crank circuit board
into the controller.
11. Reconnect leads 1, 2, and 3 to terminal strip TB1 on
the cyclic crank circuit board. See Figure 4-10.
12. Check that the generator set master switch is in the
OFF position.
13. Reconnect the generator set engine starting
battery, negative (--) lead last.
14. Reconnect power to the battery charger, if
equipped.
