Pump group module (for 1 pump group)

• Function Description

  The pump group module (PGM01) is equipped with the necessary I/Os for controlling a single pump group or convector(s). By entering the serial number of the pump group module in System Manager III, you can easily create the required I/Os and underlying logic automatically. The pump group module is suitable for controlling various types of pump groups and convectors. Both pump groups with 3-point control via 230V control contacts and valves controlled via 0-10V can be connected. 

  The module has 4 potential-free contacts of 10A each for controlling a pump and a 3-way valve. There is one 0-10V control for the control of a three-way valve. Two NTC sensors can be connected for temperature measurements. There are 3 freely programmable inputs provided for potential-free contacts.

  The PGM01 is connected to the two-wire bus of a CTD. Once the CTD has an internet connection, the operation and visualization of the outputs can be displayed via Qbus Cloud, Qbus Control App, EQOmmand, and other visualisation software that can be linked.

  A safe working mode can be configured in case communication with the CTD is lost.

  If devices with heavy inductive loads, with large capacity, or when bipolar applications need to be connected, you must use a contactor. A relay contact of the PGM01 will then activate the coil of the contactor. 

  The PGM01, like every Qbus module, has a unique serial number that is entered in the configuration software System Manager III during configuration. All programmed data remain stored internally in permanent memory.

  The operating mode of the PGM01 can only be adjusted via the Qbus configuration software (System Manager III).

  The following “Modes” are applicable:

  • Bistable (relay contacts and inputs)
  • Timer 1 (relay contacts and inputs)
  • Timer 2 (relay contacts and inputs)
  • Timer 3 (relay contacts and inputs)
  • Interval (relay contacts and inputs)
  • Shutter 1T (relay contacts and inputs)
  • Shutter 2T (relay contacts and inputs)
  • Thermostat (relay contacts and NTC inputs)
  • Dimmer 1T and 2T (0-10V control and inputs)

  If the module is restarted after a power failure, the outputs will be in their last position, taking into account the safe working mode that is set.

General

• Veiligheidsvoorschriften

  Read the full manual before installing and activating the module.

  WARNING

  • The module must be installed, activated, and maintained by a certified electrical installer in accordance with the prevailing legal requirements of the country.
  • This module is only suitable for DIN-rail installation EN50022. The module must be installed in a fireproof, enclosed distribution cabinet with ventilation grids.
  • Before working on the PGM01, the power supply must be switched off.
  • Risk of injury! Ensure that no unwanted or incorrect control of the devices can occur during operations.
  • Qbus is not responsible for any damage resulting from improper handling or misuse of the module.

Installation and wiring

• Installation

  Snap the module onto a DIN rail DIN EN50022.

• Power supply

  WARNING: DISCONNECT POWER SUPPLY TO THE MODULE BEFORE WORKING ON THE MODULE!
  A double-pole automatic circuit breaker with a maximum of C10A must be connected to the 230Vac module power supply. Conductor cross-section: minimum 1.5mm² at 10A. Remove approximately 7mm of insulation from the conductor and screw the conductor into the L-N connector.

• Load

  The PGM01 is suitable per relay contact for directly powering and controlling resistive loads with a capacity of up to 10A at 230VAC (cos. phi = 1). The relay contacts are single-pole and potential-free. Both solid and stranded wires can be used. The conductor cross-section is a minimum of 1.5mm² with a maximum protection of C10A. 

  Remove approximately 7mm of insulation from the conductors and screw the conductors into the connectors. For stranded wires, wire ferrules must be crimped onto the stranded wires before inserting them into the terminals. A flat-head screwdriver of 0.5mm x 3mm can be used to tighten the terminal screw. 

  Only switch on the power after all connections have been checked and the outputs are connected.

• Inputs

  Remove approximately 7mm of insulation from the cable and insert the cable into the terminals 1 to A. Both solid and stranded wire between 0.5 – 1.5 mm2 can be used; to insert stranded wire, press with a screwdriver on the designated spot on the terminal while pushing the wire in. To release and remove wires, press on the designated spot at the top of the terminal with a screwdriver and pull the wire back.

• Bus connection

  It is recommended to use the Qbus cable or any other cable with a minimum of 2 conductors of 1mm² as the bus cable. The green shielded EIB cable can also be used if the conductors are paired to achieve a minimum cross-section of 2 x 1mm².
