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 printout 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)
If the regular 24 V AC power is interrupted (as long as an internal emergency battery is connected and the control
current is still good):
•
With analogue control, the iM.60 goes to the preferential position (predefined).
•
With control via an I/O network, adjust the iM.60 until the battery voltage is lower than 22 Volt. After this, the iM.60
will go to the preferential position (predefined).
In both cases, an A3 will be shown on the display.
When using an external emergency power supply (UPS) instead of internal batteries, the 24 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 go to the preferential
position.
5.3 Reversing the direction of rotation
Starting with software version A1.3, 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.
Reversing the direction of rotation negatively impacts precision.
After reversing the direction of rotation, the Open/Close indication on the printout is assigned the opposite
function.
To reverse the direction of rotation, perform the following steps:
1. Remove power from the motor.
2. Set DIP 8 to OFF (= inverse direction of rotation).
3. Switch the connection wires as follows:
•
Switch (2) + (3) on the connector of the manual operation switch ((2) becomes brown, (3) becomes white).
•
Reverse the potenti and – on the printout (+ (1) becomes green, - (3) becomes red); the L stays in
the same place.
•
Reverse the limiting switches on the printout (Open (4+5) becomes black, Closed (6+7) becomes brown).
4. Plug the motor in and perform the adjustment procedure again.
5.4 Connecting the maximum thermostat
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 .
