7.2 Detailed setup for dual-pump system
(always use two Emotron DCMs)
Setting up of the Emotron DCM
The steps below illustrate examples of how to program the DCM. When the
power is turned on, press to proceed to the next window, press or
to increase or decrease the value and press to confirm the new value in each
window. For quick setup, see Chapter 4.
1. In window 71 set the required function: dual-pump control MASTER (2)
for one of the DCMs and for the other DCM dual-pump control SLAVE
(3). The DCM MASTER must be the DCM that is wired for MASTER, see
Fig. 16, page 36.
2. In window 72 on the MASTER DCM, set the condition for alternating the
pumps. Alternate by each pump cycle (on). The SLAVE DCM starts only
when the DCM MASTER shows fault codes (OFF).
3. In window 73 on the MASTER DCM, set the condition for pump start-up
on the high-level switch. Both pumps start (on). One pump starts (OFF).
4. In window 13 select the type of Auto set (on both DCMs). Set the window
to (
-
) if the pump is pumping without snoring (there is liquid in the pit).
Set the window to (_) if the pump is snoring (no liquid in the pit); see Fig.
12, page 24.
5. In window 22 on the MASTER DCM, set the maximum pause time
between 0 - 720 minutes.
6. In window 23 on both DCMs, set the required start-up delay between 1-
170 seconds. Start-up delay time is the time between the pump starting and
the time when snoring is detected (no liquid in the pit).
WARNING: The pumps start and stop during setup. Make sure
that all safety measures have been implemented before
switching on the supply voltage and starting the pumps in order
to avoid personal injury.
NOTE: To prevent involuntary starting and stopping of the pumps during
setup steps 1 to 14, disconnect the wire on terminal 8 on both DCMs.
