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 7 the module s internal memory and are retained even when the unit is not powered. To mount the module, drill a single 5.5mm / / hole, locate its 32 screw threaded stud through the hole and secure with the washer and nut provided. The module s 8 connection wires pass through the hollow stud into the target application. A rubber seal is included, providing splashproof protection for the unit when fitted to the meter during installation.

SAFETY To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the modules 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).

Black 0V Negative power supply connection. 1. Brown RANGE Do not connect for 99999 Hour range. Connect to 0V for 9999.9 Hour range. 2. Red V+ Positive power supply connection. 3. Orange V-SENSE 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. 4. Yellow PULSE Normally at 0V, this output goes High (+3.3V) every hour in the selected mode. 5. Green LZB 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. 6. Blue RESET Connect momentarily to 0V to reset the display to zero (internally connected to V+ via pull-up resistor). 7. Violet TRIP/TOTAL 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. 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 againstload dum conditions, transients, etc. DISPLAY FUNCTIONS 8888.8 The 5 digit readout displays elapsed time in hours.
