EMC Single Hole Mounting Elapsed Hour Meter
EMC is an easy to mount LCD digital elapsed hour meter. The module features 9999.9 and hour ranges, resulting in 1/10 hour and hour resolution respectively. 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 single 5.5mm hole, locate its screw threaded stud through the hole and secure with the washer and nut provided. The module's connection wires pass through the hollow stud into the target application. rubber seal is included, providing splashproof protection for the unit when fitted to the meter during installation.

Frequently Asked Questions
How do I physically mount the EMC 1500 module?
Drill a single 5.5mm hole, fit the included seal, and secure the module from behind using the screw threaded stud, washer, and nut provided.
What are the recommended voltage limits for connecting the wires?
To adhere to the Low Voltage Directive (LVD), input voltages must not exceed 60V d.c. The user should also ensure it complies with BS EN 61010.
Can I use the module in 'Total' mode or 'Trip' mode?
The meter supports both modes. The Trip/Total wire (Violet) is used to select them, and the elapsed hour can be reset in Trip mode but not in Total mode.
What is required to ensure leading zeros are blanked out when counting hours?
Connect the Green Leading Zero Blanking (LZB) wire; however, connecting it momentarily to 0V will only blank zeros if the reading is non-zero.
