No control signal (communication)
If the iM.60 is included in an I/O network and communication is interrupted, then the A4 alarm will appear after 6
minutes. Independent regulation will occur if a temperature sensor is connected. The regulation's basic principles
are:
• The current temperature becomes the set point temperature.
• The current valve position becomes the minimal valve position or - if lower - the predefined valve position.
The intelligent module will calculate the air intake position itself based on the temperature measurement and the
settings. In this case, an L will be displayed on the display of the circuit board by pressing the pushbutton. If no
temperature sensor is connected, the predefined position will be sought. An L appears on the display.
Loss of power (power failure)
When using an external emergency power supply (UPS) the 230 V AC will not be interrupted. The UPS must,
however, be equipped with a Power Fail (PF) output (normally open contact) that connects the PF input on the
iM.60 whenever regular mains power is interrupted. The iM.60 will send the actuator to the preferential position.
An A3 will be shown on the display.
The direction of rotation of the propulsion motor can be reversed. This possibility is used whenever the connection
has been made in the opposite direction. This procedure is only for iM.60 with CPS. (Contactless Position
Sensor).
Always restore the factory settings before changing the direction of rotation.
Don’t switch the CPS wires connected to the circuit board. This will damage the CPS.
After reversing the direction of rotation, the Open/Close indication on the circuit board is assigned the
opposite function.
To reverse the direction of rotation, perform the following steps:
1. Restore the factory settings (see page 20).
2. Switch off the power from the iM.60.
3. Set DIP 8 to OFF (= inverse direction of rotation).
4. Switch the connection wires as follows:
• Switch wires (2) + (3) on the connector of the manual operation switch. (2) becomes brown, (3) becomes
white).
• Switch the limiting switches on the circuit board (Open (4+5) becomes black, Close (6+7) becomes
brown).
5. Switch on the power.
6. Perform the adjustment procedure again (see page 11).
You may connect a maximum thermostat as an extra security. The air intake will open completely whenever the
maximum thermostat is activated. The maximum thermostat and a remote control may be switched in parallel.
The maximum thermostat also takes precedence over (overrules) the manual control.
This operating possibility works only if the motor's rotating switch is set to A.
