12. Push the manual override button, and turn the actuator coupling manually to ensure the actuator can rotate from
full-closed to full-open positions without binding.
13. Complete the mounting by rotating the damper to the full-open position.

Field Controller (FC) Bus
The field controller (FC) Bus terminal block is a blue, removable, 4-terminal plug that is keyed to only fit in to the board-
mounted, gray FC Bus jack. Wire the removable FC Bus terminal block plugs on the SE-ZEC Controller and other FC Bus
controllers in a daisy-chain configuration using 3-wire twisted, shielded cable.

SE-ZEC Controller Address
SE-ZEC Controllers are master devices on BACnet MS/TP (SA or FC) Buses. Before operating field controllers on a Bus,
you must set a valid and unique device address for each controller on the Bus. You set a field controller’s device address
by setting the positions of the switches on the devise address DIP switch block at the top of the controller. Device
addresses 4-127 are the valid addresses for the SE-ZEC controller. SE-ZEC Controllers ship with all address switches set
to ON. Set a valid and unique device address on the field controller before applying power to the controller on the Bus.
The DIP switch block has eight switches numbered 128, 64, 32, 16, 8, 4, 2, and 1.
To set the device addresses on a ZEC field controller:
1. Set all of the switches on the field controller’s device address DIP switch block (128 through 1) to OFF.
2. Set one or more of the seven address switches from 64 to 1 to ON, so that the sum of the switch numbers set to ON
equals the intended device address. Set the highest number switch that is less than or equal to the intended device
address to ON. Then continue setting lower numbered switches until the total equals the intended address.
For example
: If the intended device address is 21, set the switches so that 16 + 4 + 1 = 21.
a. Set switch 16 to ON
b. Set switch 4 to ON
c. Set switch 1 to ON
3. Set a unique and sequential device address for each of the field controllers connected on the FC Bus, starting with
device address 4. To ensure the best Bus performance, set sequential device addresses with no gaps in the device
