The 5 digit readout displays elapsed time in hours.
This symbol is displayed when trip mode is selected (see Wire Functions above)
This symbol is displayed when total mode is selected (see Wire Functions above)
The 10-segment incrementing bar indicates that the module is working correctly and counting hours.
Basic 3-wire operation:
Open S1 to read TOTAL value
without counting hours.

- Leading Zeros are displayed
- Timing in TOTAL mode
- Leading Zeros are displayed
- Timing in TRIP mode
Do not connect the following wires to V+: RANGE, PULSE, LZB, RESET, TRIP/TOTAL, as this may
damage the meter. The user must incorporate suitable protection circuitry in applications where
the voltage to any of the meter's wires can exceed 27V d.c., including transient conditions, else
damage to the meter may occur. In particular, for applications in harsh electrical environments,
e.g. automotive, suitable external protection must be provided to protect against "load dump"
conditions, transients, etc.

Negative power supply connection.
Do not connect for 99999 Hour range.
Connect to 0V for 9999.9 Hour range.
Positive power supply connection.
Connect to V+to start/continue counting elapsed hours.
Connect to 0V or do not connect to read TRIP or TOTAL value without counting elapsed hours.
Normally at 0V, this output goes High (+3.3V) every hour in the selected mode.
Do not connect to display leading zeros.
Connect to 0V to blank all leading zeros.
When reading is 0000.0 or 00000, leading zeros are not blanked.
Connect momentarily to 0V to reset the display to zero (internally connected to V+ via pull-up resistor).
Do not connect for TOTAL mode operation. In TOTAL mode, the elapsed hour meter cannot be reset to zero.
Connect to 0V for TRIP mode operation. In TRIP mode, the elapsed hour meter can be reset to zero.
