EMC 1500

Single Hole Mounting Elapsed Hour Meter 

## **EMC 1500** 

## _eee-— No: 716 - Page 1 of 2 

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 when the unit is not powered. To mount the module, drill a single 5.5mm / / " hole, locate its 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 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 ElectricalEquipmentforMeasuring,ControlandLaboratoryUse).

**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.**
