1. General description
The relay module is an expansion module for circulator pumps GRUNDFOS
MAGNA 25-60, 25-100, 32-60, 32-100, 40-100, 50-100.
Note: The relay module cannot be used for MAGNA D 40-100 (twin-head
pump).
The relay module is used for the control and monitoring of the pump. The
pump can be started/stopped via an external relay and give fault, ready or
operating indication. The functions can be utilised via an external control
system, e.g. a building management system.
The relay module offers the following functions:
•External start/stop,see section 4.
•Fault, ready and operating indication via signal relay,see section 5.
2. Connection
The electrical connection and protection must be carried out in accordance
with local regulations.
Prior to installation, read these installation and operating instruc-
tions. Installation and operation must comply with local regulations
and accepted codes of good practice.

The relay module is powered wirelessly from the pump. To ensure correct
function, follow the instructions in section 3.2 Mounting the module.
Connect the module as shown in fig. 1.
Note:
• All cables must be heat-resistant up to +85°C.
• All cables must be installed in accordance with EN 60204-1.
Fig. 1 Connection terminals
A connection example is shown on page 6.
Wires connected to
• the outputs NC, NO, C and
• the start/stop input
must be electrically isolated from each other.

3.2 Mounting the module
TM03 0881 0705
1. Localise the two hooks on the
module.
2. Gently push the module into
place so that the hooks en-
gage with the control box.
TM03 0880 0705
3. Check that the module and
the control box bear against
each other.
4. Check that the two hooks of
the module engage correctly
with the control box.
5. Fasten the module with the
screw.

4. External start/stop
The relay module incorporates a digital input for an external contact.
The pump can be started and stopped via this input.
When started, the pump will operate with the setpoint set on the control
panel or with the R100.
Note: If the external contact is used, the connection between terminals
7 and 8 must be replaced by the external connection.
Functional diagram: Start/stop input
5. Signal relay
The function of the signal relay can be set with the R100.
Possible functions:
•Fault
• Ready
•Operation.
5.1 Fault indication
The signal relay is activated in case of
• Pump blocked
• Internal fault
•Undervoltage.
See section 5.4 Functional diagram.
When the fault disappears, the signal relay is deactivated. The fault cause is
stored in the pump alarm log. The latest five faults can be called up with the
R100.
Note: In case of a fault, the red indicator light on the control panel is on.
See installation and operating instructions for GRUNDFOS MAGNA 25-60,
25-100, 32-60, 32-100, 40-100(D), 50-100.

5.2 Ready indication
The signal relay is active when the pump is in operation or ready for opera-
tion.
See section 5.4 Functional diagram.
5.3 Operating indication
The signal relay is active as long as the pump is operating. If the pump is
stopped on the control panel, with the R100 or because of a fault, the signal
relay is deactivated and consequently gives a signal to an external control
system, e.g. a building management system.
See section 5.4 Functional diagram.

6. Priority of settings
The external forced-control signals will influence the settings available on the
pump control panel and with the R100. However, the pump can always be
set to max. curve duty or to stop on the control panel or with the R100.
If two or more functions are activated at the same time, the pump will operate
according to the setting with the highest priority.
The priority of the settings is as shown in the table:
Example: If the pump has been forced to stop via an external signal, the
pump control panel or the R100 can only set the pump to max. curve.
