Product Data ELECTRONIC PRESSURE MEASUREMENT PRODUCTS Model DDMC Digital Meter/Controller Meter Copy Manual Output Control The Copy function is a standard feature used to copy (or clone) all the settings from one meter to other meters requiring exactly the same setup and programming (i.e. type of input, scaling, decimal point, filter, bypass, etc.). Take control of any output with this feature. All relays can be forced ON or OFF, and the 4-20 mA output signal can be set to any value within its range. When the relays and 4-20 mA output are controlled manually, an LED labeled “M” is turned on...

Product Data ELECTRONIC PRESSURE MEASUREMENT PRODUCTS Model DDMC Digital Meter/Controller Multi-pump Alternation Up to 8 pumps can be aternated and sequenced with the DDMC digital meter/controller. Relay #2 trips the High Level Alarm at 7500 gallons and resets at 6900 gallons. Relay #4 turns the main pump on at 6000 gallons and turns it off at 1000 gallons. With the Pump Alternation feature activated, the next time the level reaches 6000 gallons, relay #3 transfers and starts the backup pump. Relay #1 trips the Low Level Alarm at 495 gallons and resets at 750 gallons. If the backup pump is...
