SWITCHMATIC 2T SERIES CONTROLLER

TYPE
Note 3:
Choosing "no" (normally open) allows us to place the SW 2T as an auxiliary pressure
control element in the pump suction) and stop it if it does not reach the PStop. It will start
again when the suction pressure reaches the configured PStart.
Example:
- PStop: 0.9 bar
- PStart: 1.2 bar
12. SYNCHRONIZATION
The SWITCHMATIC 2T can be synchronized with another SWITCHMATIC 2T unit, managing
and protecting two pumps operating in cascade with alternate start-up sequence. To
calibrate the synchronization, the following steps must be followed:
1. GO TO ADVANCED MENU:
- In step 2: select E01 on one unit (this will be the MASTER) and E02 for the other unit (this
will be the SLAVE).
- In step 3: select the same offset parameter d.XX. It is the difference between the main and
auxiliary pump start-up pressures or also between the stop pressures.
