• The Protect-Module C must be protected during transport and storage from moisture, frost and mechanical damage.
• It must not be exposed to any temperature outside the range – 10 °C to + 70 °C.

Application

The TOP series circulating pumps come equipped with a standard terminal box.
A retrofit plug-in module is available for the pump with the Protect-Module C (see title illustration). In addition to the pump functions, the Protect-Module C also enables further signals as well as the performance of control tasks.
When the Protect-Module C is deployed, external contactors and supplementary switchgears are no longer required, with a corresponding effect on the complexity of the installation.

Product data

Type Key

Technical data

Scope of supply

• Protect-Module C
• Plug strip control and signal terminals
• Plug strip mains connection terminals and connection terminals WSK/SSM with connection cables
• Fixing screws (4)
• Installation and operating instructions

Description and function

Description of the Protect-Module C

The functions of the pump housed in the terminal box (mains connection, thermal winding contact WSK or potential-free collective fault signal) are transferred to the terminal box when the Protect-Module C is installed. The fault acknowledgement button and the direction of rotation control lamp, if fitted, as well as the manual speed stage switching of the standard terminal box continue to function when the Protect-Module C is installed.
The Protect-Module C is fitted to the standard terminal box of the pump in place of the terminal box cover.

Functions and operation of the Protect-Module C

Light signals

There are three possible light signals on the display field:

• Operation light signal (figure 1, position 1)
  WARNING! Danger of electric shock
  Even when the operation light signal is off, voltage may be present on the Protect-Module.
• Fault signal light “Stoppage” (figure 1, position 2)
• Fault signal light “Winding Overheat” (figure 1, position 3)
  

Fault acknowledgement buttons

• Fault acknolwledgement button on the pump (figures 3b, 3d, position 4) If fitted, this button is used to reset the response of the integrated full motor protection. This fault reset is done before fault reset on the Protect Module C.
  
  
• Fault acknowledgement button on Protect-Module C (figure 1, position 4)
• A fault displayed on the Protect-Module C is reset by briefly pressing this button (< 1s).
• Pressing and holding down the button (≥ 1s) triggers pump cycling in dual pump operation with integrated dual pump management.

Faults, light signals, signal contacts

• Single pump
  The following table shows the links between possible faults and the reactions of light signals and signal contacts:

Table 1

1. After acknowledging a fault, the Protect-Module C will be in a special control loop for up to 10 sec, depending on pump type and fault. If the fault is recognised again during this process, the pump returns to fault status.

• Double pump:
  The relationships between possible faults and the reactions of light signals and signal contacts depend on the following factors:
• Parametrisation of signal contacts in individual operation/individual fault signal or joint operation/collective fault signal (function see Table 2)
• Allocation of “Ext. Off” control inputs to master and slave

Double pump operation

A Protect-Module C must be installed for each of the two pumps.
The double pump functions on the Protect-Module C are:

• Main/Reserve operation with automatic switching to the standby reserve pump after 24 hours of real running time, the external control command “Ext. Off” interrupts the running time counter.
• Switching takes place through an overlap, i.e. at the time of switching, both pumps run simultaneously (for approx. 10 sec.). This avoids pressure surges and undersupply in cooling and air-conditioning systems for example.
• The DIP switch 1 (figure 2b, position 1) determines which pump is the master (MA) and which pump is the slave (SL) (function see Table 2).
• The DIP switch 2 (figure 2b, position 1) determines whether the signal contacts “SSM” and “SBM” are individual or collective signals (function see Table 2).
• In the case of a fault in the working pump, the system switches to the standby pump after approx. 3 sec.

Table 2

Installation and electrical connection

Installation and electrical connection must be carried out in accordance with local regulations and only by qualified personnel.
WARNING! Danger of personal injury
The applicable regulations on the prevention of accidents must be observed.
WARNING! Danger of electric shock
Potential dangers from electrical currents must be eliminated.
Local directives or general regulations [e.g. IEC, VDE etc.] and those issued by the local power supply company must be adhered to.

Installation and electrical connection of mains cable

1. Switch off power supply to pump,
   CAUTION! Danger of damage to Protect-Module C
   The module may only be plugged in and unplugged when the pump has been completely disconnected.
2. Loosen the terminal box lid screws on the pump,
3. Remove terminal box lid,
4. Pinch off power supply cable except the protective lead PE:
   EM version (1~230V): L, N
   DM version (3~400V) L1, L2, L3 (figure 2a)
   
5. Remove plug strip with power supply terminals and connection terminals MP1/MP2 (figure 2b, position 5) with connection cables (figure 2b, position. 2.3) from the Protect-Module C. When removing, do not pull straight out, but begin at one corner of the plug strip,
   
6. Apply the plug strip cables to the corresponding terminals on the pump terminal box (figure 2c, figure 3),
   
   
7. Fit power supply cable to the plug strip, Table 3 shows the allocation of module types to the terminal diagrams.
   Table 3

   Protect-Module C	Terminal diagram
   Type 22 EM Type 32-52 EM Type 22 DM Type 32-52 DM	3a 3b 3c 3d

8. Remove the plug strip with control and signal terminals (figure 2b, position 4) from the Protect-Module C. When removing, do not pull straight out, but begin at one corner of the plug strip,
   1. Dismantle cable connection (PG 9) of the Protect-Module C,
   2. Cut diaphragm seal,
   3. Thread individual parts of the cable connection onto the control cable (figure 2d),
      
      Pos. 1: Union connection
      Pos. 2: Seal
      Pos. 3: Strain relief
   4. Insert control cable through cable connection into Protect Module C,
   5. Assemble cable connection, fastening union nuts tightly enough so that the cable can no longer be pulled out of the cable connection by hand
      CAUTION! Danger of damage to Protect-Module C
      An incorrectly assembled cable connection may lead to a short circuit in the module due to water penetration. This is a particular danger in cold water installations in which condensation constantly forms.
9. Fix control cable to the plug strip (figure 2 e),
   
10. Plug the plug strip with control cable to the corresponding place in the Protect-Module C,
11. Set DIP switch (figure 2b, position 1) in accordance with Table 2,
12. Plug the Protect-Module C on to the plug strip with the power connections (figure 2f),
    
    Note: Arrange power cables and leads so that they cannot be crushed when finally tightening the module installation.
    In DM versions, it is essential before final tightening of the module installation to check the direction of rotation with the direction of rotation control lamp in the pump terminal box (figures 3c, 3d, position 1).
    
    
13. Arrange the Protect-Module C over the terminal box structure and screw to the domes of the terminal box using the screws provided, tighten screws evenly diagonally (figure 2g). 
    • Stages 1 to 4 are not required for a new installation. Power connection is made directly on the corresponding plug strip with power connection terminals and connection terminals MP1/MP2.
    • For a double pump, as previously described, two Protect-Modules C must be fitted. For integrated dual pump management, the DP terminals of the two Protect-Modules C must be connected to each other, see also figure 3e.
      

Electrical connection of control and signal clamps

For connection to a remote control centre or building automation, the following connections are provided:

• Ext. Off: Control input with “drive priority off” for potential-free normally closed contacts, contact charge 24V, 10 mA.
  In dual pump operation, Ext. Off on the master must be assigned to a potentialfree normally closed contact, and Ext. Off on the slave must remain bridged. The Ext. Off of the master works on the entire double pump, i.e. master and slave.
• SBM: Programmable run signal, potential-free normally opened contact, maximum contact capacity 250 VAC, 1 A.
• SSM: Programmable fault signal, potential-free normally closed contact, maximum contact capacity 250 VAC, 1 A.
  A serial interface is provided for integrated dual pump management:
• DP: Interface for integrated dual pump management, the connection terminals cannot be twisted. The connection cable (2 x 0/75 mm2 ) must be provided on site. Wiring for all Protect-Modules is shown in the example in figure 3e.
