Introduction
Emotron AB 01-2120-01r2
The Emotron DCM always stops the pump as soon as it starts to snore (draw
air) and restarts it after a calculated pause time or in response to a high-level
switch-over.
The Emotron DCM is able to check:
•
Phase sequence.
•
Phase voltage asymmetry.
•
Current from current transformer(s).
•
Temperature on pump motor.
•
Undervoltage and Overvoltage (at start up).
The Emotron DCM gives information about:
•
Delay time before restarting after the pump has stopped.
•
Pumping time since the latest pump start.
•
High-level pumping time since the pump started as a result of high-level
switch-over.
•
Measured power as a percentage of the DCM’s measurement range.
•
Measured voltage.
•
Measured peak power as a percentage of the DCM’s measurement range.
•
Time counter for total pumping time.
•
Start counter - total number of times pump has started.
The Emotron DCM can be connected in parallel for a dual-pump system:
•
Alternating
•
MASTER/SLAVE function
•
If there is a breakdown in one of the pumps, the other pump starts to
operate.
