Setting Parameters (continued)
Low-Voltage Indicator
V
The TM500A should be set to trigger on a user specified low DC voltage
level. When the battery voltage falls below this level, the VOLTAGE indicator
(
V
) flashes approximately once every four seconds. This meter is useful to
determine if the batteries are being over-discharged. Refer to the battery
manufacturer’s specifications for the proper low-voltage level.
A voltage between 10 and 35 volts (10 and 64.9 volts for 48-volt
systems) can be specified to activate the low-voltage alarm.
NOTE: Disconnecting the TM500A from the shunt (DC voltage) will
cause this setting to be reset to 0.00. It must be re-configured again
for the proper system low voltage level.
Configuring the Low-Voltage Alarm
1. Press and hold the SELECT button until the dSF message is displayed,
then release.
2. Press and release the SELECT button until the bLO message is
displayed in the LED display.
3. Press and release the SELECT and RESET button simultaneously.
NOTE: Pressing the RESET button alone while bLO is displayed will
reset the meter to the current battery voltage.
4. Press the RESET button until the desired voltage level is displayed.
5. Press the SELECT button to accept this value.
6. Press the SELECT button to return to the metering mode.
