Circulation pump control module РSM. Danfoss has released a new line of pump station control controllers
ATTENTION!
Dear Clients!
Danfoss has released a new line of control controllers pumping stations.
Danfoss PCM microprocessor control modules are designed to control, monitor and prevent emergency situations at pumping stations in heat, cold supply and water treatment systems. This line is based on the freely programmable MCX controller with preinstalled software.
Distinctive feature These controllers are easy to configure and integrate into complex automation systems of heating points. PCM devices synchronize with any supervisory control system.
For the convenience of working with PCM, they can be connected to an external display MMIGRS2 on the front panel of the automation cabinet (case protection degree IP64), which avoids unnecessary penetrations into the cabinet to check the status of the controller and make adjustments to its settings. There are five in total in the new line ready-made solutions for automation of pumping equipment:
PCM CWS- a controller designed to regulate water pressure in cold water supply systems, booster, stepdown and mixing pumping stations with cascade connection of up to four pumps in one pump group.
Three operating algorithms are supported: each pump in a group with a personal frequency converter (FC), one frequency converter per group of pumps, and operation of all pumps from the network or a soft starter.
PCM CP- a controller designed to control up to three circulation pumps in a group, providing circulation support in hot water supply, heating, and cooling systems.
PCM RP- a controller for controlling one or two pumps in a group, ensures support of the required volume of liquid in the main system due to its replenishment. Can be used as a locking device solenoid valve, a control valve with an electric drive (three-position control), or a ball valve with an electric drive.
PCM DP- a controller designed to control a group of two drainage pumps, providing pumping (removal) of groundwater and liquid as a result of flooding of a heating point. The controller operates using three level sensors.
PCM MM- a controller designed for building on its basis systems for remote monitoring and automation of process control, water and heat supply for heating points, and dispatch control systems.
The universal controllers of this line are distinguished by their small dimensions, reliability and full compatibility With frequency converters and Danfoss sensors.

Pump control module MCX CP(new designation PCM CP) is a microprocessor controller with pre-installed software, designed to control up to three circulation pumps in a group, providing circulation support in hot water supply, heating, and cooling systems.
Module MCX CP developed on the basis of Danfoss MCX series controllers. The basic ones are the controller MCX06D and expansion module EXC06D.
Application area:
- Automation of central heating centers;
- Automation of ITP;
Part of the equipment:
The MCX CP pump module provides system control in the following configuration (for three pumps):
- Three pumps (P1,P2,P3);
- Two analog pressure sensors (4-20 mA) for differential control (S2, S3);
- Two discrete sensors from dry start-up, to control the pressure drop (S1, S4);
- One discrete differential pressure sensor for each pump (S5, S6, S7);
Functionality of the MCX CP pump module:
Two control algorithms circulation pumps.

- Starting the module using logical and automatic starts;
- Automatic, semi-automatic and manual pump control modes;
- Tracking feedback from pump motors;
- Possibility of transmitting control signals to external devices(signals about pump switching);
- Automatic leveling of pump resources;
- Possibility of resetting the operating time of each pump in the group;
- Contains the ability to connect and analyze a sufficient number of sensors to monitor the operating state of the system;
- Monitoring of pump and group failures, sensor states, etc. System response depending on the level of emergency;
- Possibility to accept one accident from each pump. For example, when a thermal relay is triggered;
- Indication of the presence of accidents in the system and on each pump;
- Independence from the factory settings of the expansion module. Constant monitoring of the presence of communication with the controller;
- Possibility of data exchange with PC/communication controller.
Circulation pump control circuits
Control of a group of two pumps, when only one of the pumps is running at the same time, the other is a backup. Pump rotation is provided. Switching between pumps is carried out:
- by accident;
- according to operating hours.
The central heating module begins its operation by starting the pump with the fewest operating hours. After working for a specified period of time (operation period), the pump stops. Now he is a reserve. After a specified time interval, another pump starts.

Control of a group of three pumps, when two pumps are running simultaneously (50% and 50%), the remaining of the three is a backup. Pump rotation is provided. Switching between pumps is carried out:
- after a specified period of pump operation;
- by accident;
- according to operating hours.
The operation of the central heating module begins with the start of the pump with the fewest operating hours. After a specified time interval, the next pump starts. Each of the operating pumps, having worked for a given period of time (operation period), stops. The standby (currently idle) pump starts.
Thus, pump 1, which started first and worked for a given period of time (operation period), stops. Now he is a reserve. After a specified time pause, pump 3 starts. Pump 2 was started a pause after starting pump 1, so it will stop later than pump 1. After a specified time pause after stopping pump 2, the current backup pump 1 starts. Now pump 2 is a backup. When the third pump has worked for a specified period of time (operation period) and stops, after a specified time pause, pump 2 will start, and pump 3 will become a backup.
