EMC 1500 User Manual
EMC 1500 Single Hole Mounting Elapsed Hour Meter
EMC 1500 is an easy to mount LCD digital elapsed hour meter. The module features 9999.9 and 99999 hour ranges, resulting in 1/10 hour and 1
hour resolution respectively. A leading zero blanking input is provided allowing the user to switch off unwanted leading zeros. The module
incorporates an output that pulses high after every hour counted. This is particularly useful in applications where maintenance or inspection is
required at regular time intervals. The timer features Trip and Total ranges. The Trip range can be reset to zero. The meter's readings are stored in
the module's internal memory and are retained even whenthe unit is not powered. To mount the module, drill a single 5.5mm/ / " hole, locate its
screw threaded stud through the hole andsecure with the washer and nut provided. The module's 8 connectionwires pass through the hollow stud
into the targetapplication. A rubber sealis included, providing splashproofprotection for theunit when fitted tothe meter duringinstallation.

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 forMeasuring,Control and Laboratory Use).

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 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.

When reading is 0000.0 or 00000, leading zeros are not blanked.
Connect to 0V for TRIP mode operation. In TRIP mode, the elapsed hour meter can be reset to zero.
