FP-CPM. New control module for speed controllers and EC fans

Russian refrigeration components plant Frigopoint has started production of a new control module for speed controllers or EC. The FP-CPM control module is designed for installation on refrigeration units in order to maintain a set condensation pressure level in the system by supplying a 0-10 V control signal to the condenser fan speed controllers or EC fans. The device has a pressure measurement port; the output control voltage changes according to a proportional algorithm relative to the condensation pressure setpoint (adjusted by the screw on the top cover).
The CPM control module operates on the principle of changing the output voltage of 0...10 volts in accordance with the measured pressure and the setpoint. The working diagram is shown in the
figure below. There is an adjusting screw on the front panel, one turn of which corresponds to a change in the setpoint by 0.8 bar (increase - clockwise, decrease - counterclockwise).

The regulator can be mounted vertically (with the adjusting screw facing up):

A. Directly on the pipe to the service nipple (Fig. 2A); In this case, mounting is only permitted on the liquid pipeline. Installation on the "compressor-condenser" discharge line is not permitted.
B. On the panel using a mounting bracket (Fig. 2B) and subsequent mounting of the connecting tube to the regulator nipple. In this case, mounting is permitted on the liquid pipeline and on the discharge line.
The technical characteristics of the regulator are presented in the table:
