8.4 BATTERY OVERTEMP CUT-OFF.
8.4.1. Settings:
8.4.1.1. Set current selectors to zero.
8.4.1.2. Set the timer speed switch in the normal position (to the right).
8.4.1.3. Set time selectors to 1/01 and cell selector to 20.
8.4.1.4. Connect the battery cable to the unit but make no battery or Temp-
Plate connections. The red Overtemp light will be on.
8.4.2. Temp-Plate simulations resistors:
8.4.2.1. Connect one 16.5 K-OHM (1%) resistor between pins D and B
8.4.2.2. Connect one each 30.1 K-OHM (1%) resistors between pins D and C,
D and E, and D and H.
8.4.2.3. The red light will turn off.
8.4.3. Start in either of the charge modes.
8.4.3.1. The unit will start and immediately go into Overtemp fault (red light
flashing and alarm on).
8.4.3.2. Reset.
8.4.4. Repeat the previous test by rotating the 16.5 K-OHM resistor in all four
positions.
8.4.5. Repeat the first test using four 17.5 K-OHM (1%) resistors.
8.4.5.1. The unit must not show Overtemp fault.
8.5 VOLTAGE FAULT TEST.
8.5.1. Disconnect battery cable from any external devices.
8.5.2. Settings:
8.5.2.1. Set the Current Selectors (both) to 010.
8.5.2.2. Set the Time Selectors to 1/01.
8.5.2.3. Set the Cell Selector to 20.
8.5.3. Start in either of the charge modes.
8.5.3.1. The unit will start and the output voltage will slowly rise.
8.5.3.2. The unit will stop, indicating a voltage fault.
8.5.3.3. Reset.
