Display Functions - LASCAR EMC 1500 Mode D'emploi

ENGLISH
SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module's wires must not exceed 60Vd.c. The
user must ensure that the incorporation of the meter into equipment conforms to the relevant sections of BS EN 61010 (Safety
Requirements for Electrical Equipment for Measuring, Control and Laboratory Use).
WIRE FUNCTIONS
0. Black 0V
1. Brown RANGE
2. Red V+
3. Orange V-SENSE
4. Yellow PULSE
5. Green LZB
6. Blue RESET
7. Violet TRIP/TOTAL
WARNING
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 V+ (or voltage sense) could 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.

DISPLAY FUNCTIONS

The 5 digit readout displays elapsed time in hours.
TRIP
This symbol is displayed when trip mode is selected (see Wire Functions above)
TOTAL 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.
CONNECTIONS
0. Black 0V
1. Brown 9999.9/99999
2. Red V+
3. Orange Voltage Sense
The EMC 1500 LCD digital elapsed hour meter features 9999.9 and 99999 hour ranges, resulting
in 1/10 hour and 1 hour resolution respectively. The module incorporates an output that pulses
high after every hour counted. This is particularly useful in applications where maintenance or
inspection is required regularly. The timer features Trip and Total ranges. The Trip range can be
reset to zero.
• 9mm / 0.35" LCD Digit Height
• 9999.9 and 99999 Hour Ranges
• Reset and Trip/Total Inputs
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 100 hour interval in TRIP mode.
Do not connect to display leading zeros.
Connect to GND 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 high
(+3.3V) 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 GND for TRIP mode operation. In TRIP mode, the elapsed hour meter can be
reset to zero.
