6.7 OPERATING NOTES AND PRECAUTIONS
6.7.1. Make sure that the instrument is in the reset position before turning power on or
off, or before connecting or disconnecting batteries.
6.7.2. When a cycle is terminated either automatically or by resetting, wait about two to
three seconds before re-starting in any mode (the control switch circuit has a time
delay that ignores switch selections during a 2 to 3 second interval).
6.7.3. It is possible to alternate between the two discharge modes or from the dual rate
to the single charge rate mode while the unit is in operation, but the charger must
be reset before switching to an opposite mode (e.g. from charge to discharge or
vice versa).
• NOTE: The control switch circuit ignores mode change requests without
previous resetting of the charger.
6.7.4. If the discharge current limiter opens it is still possible to operate in the charge
mode (by setting the switch in the Monitor board to Test), but if the charge
current limiter opens, the unit is rendered completely inoperative.
6.7.5. It is imperative that the current limiter and fuses be replaced with the same type
and value.
6.7.5.1. Failure to do so will result in serious damage to the control and power
circuitry of the instrument.
6.7.5.2. Failure to observe this requirement will void the warranty.
6.7.6. Do not block air circulation. A substantial amount of heat must be dissipated,
particularly in the discharge mode (up to 1KW).
• External heat removal (circulating fan) is required when operating in
confined spaces or hot environments.
6.7.7. Do not disconnect the battery cable while the unit is in operation.
• Large current surges can occur, with corresponding arcing, that can damage
the charger, the connectors and the battery.
6.7.8. Disconnect batteries and power from the instrument (remove the line cord from
the wall outlet) before changing circuit boards and current limiters or to perform
maintenance or repairs.
• Failure to do so can result in serious (lethal) personal injury and/or serious
damage to the instrument.
6.7.9. Do not exceed a setting of 79 in the total time selector.
• If exceeded, times will be inconsistent with the dialed settings.
6.7.10. Do not run the unit with the monitor switch in the test position (except for tests).
Loss of protection will occur.
6.7.11. Do not perform battery work on bare metal table tops.
6.7.12. Do not attempt to discharge with the Voltage Mode Selector in the CV or PEAK
positions.
• Voltage and currents faults will result depending on the battery voltage and
cell selector settings.
