Configuring relays for actuators
Each actuator you connect requires one relay for opening and one for closing.
 Power Blocks PBx-10, PB-1, and PB-3 can control one actuator.
 Power Blocks PBx-11, PB-2, PB-4, and PB-5 can control two actuators.
Configuring relays for actuators means:
 Selecting the relays
 Entering a descriptive name
A good description helps you identify the stage more easily.
 Enabling tunnel mode (if required)
For more information about tunnel mode, read Programming tunnel mode on page 34.
 Enabling rain detection (if required)
For more information about rain detection, read Enabling additional probes, deicing, and rain
detection on page 16.
 Because actuators require specific pairs of relays, configure actuator relays
before configuring other relays.
 Use the Installation and configuration worksheets when configuring Power Blocks.
The worksheets are in the back of the Power Block installation guide.
 For more information about actuators, read Programming relays for actuator
control on page 49.
For models PB-1 to PB-5 only
 To enable the actuator relays, you must have the jumpers in place on the circuit
board. When the jumper is in place, you cannot configure the relay set for any
other purpose.
 Calibrate the actuator before programming it. For more information, read the
Power Block installation guide.
 To disable actuator relays so you can configure them for other uses, remove the
jumpers. For more information, read the actuator section of the Power Block
installation guide.
To configure relays for actuators
1. In the main window, click Configuration, and then Ventilation.
2. Below Your Power Blocks, select the Power Block you want to configure and then click Configure
Power Block.
The Power Block configuration window displays.
