Description and function
6.1 Description of the Protect-Module
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.
6.2 Functions and operation of the Protect-Module C
6.2.1 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) 6.2.2 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.
6.2.3 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:
Operating element | Status | Possible causes |
---|---|---|
Operation light signal green | off | • No supply voltage. |
• Control input “Ext. Off” opened.
• Fault is present and has not yet been acknowledged.
flashing| • DP communication fault (only with double pump).
Fault signal light “Stoppage” red| off| • No motor stoppage.
on| • Motor stoppage recognised.
• Mechanical blockage of pump
• Winding fault
flashing| • Motor stoppage acknowledged, pump is in control loop 1).
Fault signal light “Winding Overheat” red| off| • No overheat.
on| • Overheat recognised.
• Pump overload
• Winding fault
• Unacceptable combination of medium tem- perature – ambient temperature
flashing| • Overheat acknowledged, pump is in control
loop 1).
Operating signal contact| open| • No supply voltage.
• Control input “Ext. Off” opened.
• Fault is present and has not yet been acknowledged.
closed| • Pump functioning, no fault recognised.
Fault signal contact| open| • Fault is present.
• Pump is still in control loop 1).
closed| • Fault-free operation.
Fault signal light “Stoppage” red| off| • No motor stoppage.
on| • Motor stoppage recognised.
• Mechanical blockage of pump.
• Winding fault.
- 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.
Table 1
• 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
6.2.4 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.

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. -
Fix control cable to the plug strip (figure 2 e),
-
Plug the plug strip with control cable to the corresponding place in the Protect-Module C,
-
Set DIP switch (figure 2b, position 1) in accordance with Table 2,
-
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). -
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 DPterminals of the two Protect- odules C must be connected to each other, see also figure 3e.
