3.7.3.5
– FIELDBUS INTERFACE (Optional on request)
Optionally, a field bus interface can be adapted to the AMS actuator by connecting a terminal block or an external socket. (additional
assembly manual available for fieldbus AMS).
3.8
– “AMS VERSION” ACCESSORIES
3.8.1
– ANTI-CONDENSATE RESISTOR (Optional on request)
The PSL-AMS actuators can be equipped with an anti-condensate resistor, when using the actuators in environments with high
temperature fluctuations or high humidity, you are advised to use an anti-condensate resistor to prevent condensate formation
Figure 7: Resistor connection
In PSL-AMS actuators, the resistor is powered using the
actuator power supply, so there is no need to be powered
separately. To replace the resistor, connect two cables to the
terminal of the motherboard as represented
in the image on the left.
The anti-condensate resistor is available in two different versions
(for 24 VAC/DC or 115-230 VAC). Choose the voltage of the
actuator based on the voltage.
Assembly of the resistor must be carried out in the position
indicated on the base, using the screws supplied, turn the cable
in such a manner they are not crushed by the main cover and not
touched by movement of the components inside the actuator.
3.8.2
– ADDITIONAL LIMIT SWITCH SETTING (Optional on request)
In the PSL-AMS there are already two position feedback switches, available as a default option. They are clean exchange contacts.
The silver-plated contacts are available (for currents between 10 Ma and 5 A, max 230 V or gold-plated contacts (for currents between
0.1 mA and 30 Ma, max 30V). Then connect to terminals 18/19 and 20/21
