8.6 REVERSE POLARITY TEST.
8.6.1. Connect the battery cable to a voltage source (CAL-100 or low current power
supply and reverse the polarity). Start at zero and advance towards -0.5V
8.6.2. The unit will show a fault through the alarm and the voltage fault light at about -
0.25V (-0.20V to -0.35V).
8.6.3. Alternatively, connect the battery cable, with the single cell adaptor, to one cell
with the polarity reversed or to a standard 1.5V battery (size is unimportant).
8.7 OVERVOLTAGE CUT-OFF.
8.7.1. Set the Current selectors to zero and Time selectors to 1/01. Set the Cell selector
to 20.
8.7.2. Connect the battery cable to an adjustable voltage source (CAL-100 or low
current power supply), set to approximately 34V and start the unit in either
charge mode.
8.7.3. Slowly increase the voltage. Unit will stop and indicate a voltage fault at 35V
±0.5V. Reset.
8.7.4. (See 8.2.5 for adjustments)
8.8 DISCHARGE VOLTAGE CUT-OFF.
8.8.1. Settings:
8.8.1.1. Set the Current selectors to zero and the Time selectors to 1/01.
8.8.1.2. Set the Cell selector to 20.
8.8.2. Connect the battery cable to a voltage source (CAL-100 or low current power
supply), set to approximately 21V and start the unit in the auto discharge mode
(blue).
8.8.3. Slowly decrease the voltage. Unit will go into cap fail at 20V ±0.3V. Reset.
8.8.4. (See 8.2.1 for adjustments)
