Operator electrical connections and start-up instructions
Important: Follow these steps carefully and in the order shown
1) Connect Power supply:
Single phase: Connect single phase power supply to terminals L/L1 and N/L2 on the 3-pole power terminals strip.
3-phase (380V 50Hz): Connect 3-phase power supply to terminals L1, L2 and L3 on the 3-pole power terminal strip.
2) Connect Push-button station for installation purposes (single phase or 3-phase):
Connect open/close/stop push button station to terminals T2 (stop), T3 (common), T4 (open) and T6 (temporary CP on close).
3) Verify motor direction:
After the electrical power connections are made and push button station is connected, manually move the door to mid-position.
Press Close button for several seconds and then press stop button. If door did not move in correct direction (or if limit cams not
moving in correct direction towards the close limit switch) see below:
Single phase operators:The operators leave the factory with correct motor and limit shaft direction according to standard door
installations. However, for special fire door, thru- wall mounting or other special door applications, the motor direction and
limit switch direction may need to be reversed. To reverse the motor rotation, interchange Red and Yellow wires on the motor
capacitor located in the control box.
NOTE: THIS OPERATOR COMES WITH AN INTERFACE MODULE INTEGRATED INTO THE
CONTROL CIRCUIT. THE PURPOSE OF THE INTERFACE MODULE IS TO ALLOW FOR
FAILSAFE MONITORING OF A MICANAN COMPATIBLE SAFETY DEVICE AS PER UL 325 (2010)
REQUIREMENTS.

13
3-phase operators (1/2 HP 380V 50Hz): If door moves in wrong direction, turn off incoming power and reverse any two of the
three incoming power supply leads to correct rotation. Press the open button and then activate the open limit to ensure door
stops. If door does not stop, interchange grey and red wires on open and close limits. Interchange white and grey wires on
advanced open and advanced close limits. Remove blue wire from advanced open limit and place it on N.O pin of advanced
close limit.
4) Adjust limit switch cams:
Using the open/close/stop push button station move door to fully closed and fully open oppositions and set limit cams to correct
position. (See Limit adjustment section C further in this manual for complete detail on the end of travel limit adjustments).
5) Activate Interface module:
After adjusting the open and close limits and verifying the motor rotation, open the door to the full-open position using the open
push button (Figure below on left).
At this point the close pushbutton wire must now be moved from terminal T6 to T5. Now connect the black wire (with blue
label) to terminal T1 as shown in figure below on right.
Note: Ensure the door is in the full open position before connecting the black wire. If door is not in full open position and
monitored photo-eyes or safety edge are not connected and operational then door will immediately move in the open
direction.

14
6) Connect safety devices
Failsafe feature: A monitored failsafe safety feature is built into the operator. The operator has provisions to connect one
primary monitored safety device as well as one or more non-monitored safety device(s).
Primary monitored safety device:
MICANAN monitored failsafe photo beams or MICANAN compatible monitored failsafe devices must be connected to
terminals P1 and P2 if momentary close on pushbutton is required (B2 mode). If not connected, door can only be closed by
constant pressure on close pushbutton. If constant pressure on close pushbutton is removed before door reaches full closed
position, then door reverses to full open.
Note: Only one monitored failsafe safety device can be connected across terminals P1 and P2.
Note: See section E for complete installation instructions for the Micanan N-1 or N-4 photocells or the FRABA photocells.
Secondary non-monitored safety device(s):
A standard 2-wire safety edge, non-monitored reflective or thru-beam photo eye or any other non-monitored reversing devices
with a N.O dry contact can be connected to terminals S1 and S2.
Note: More than one secondary non-monitored safety device can be connected to terminals S1 and S2.
Important: Do not remove resistor that is factory installed across terminals S1 and S2 unless installing a 4-wire electric edge.
4-wire electric edge Connection
A standard 4-wire electric edge can be connected across S1 and S2 terminals as a secondary safety device. Remove the factory
installed resistor across terminals S1 and S2 and install resistor across the black and white pair of wires from the electric edge
and connect the remaining black and white wire to the S1 and S2 terminals.
7) Select Mode of Operation:
C2 mode of operation (momentary on open, constant pressure on close):
The operator is wired at the factory for momentary on open and constant pressure on close. For single phase limited duty
operators, the purple wire is left unconnected. For 3-phase (1/2HP 380V 50Hz) operators, white wire is connected to terminal
T6.
B2 mode of operation (momentary on open, momentary on close):
If momentary on close is required: For single phase limited duty operators, connect purple wire to terminal #5. For 3-phase
(1/2HP 380V 50Hz) operators, remove the white wire from terminal T6 and place it on terminal T3.
The operator functions in B2 mode only when the primary monitored safety device is connected and functioning properly. If it is
not connected, operator will go into fault mode and door can only be closed by constant pressure on close and if constant
pressure on close is removed before door reaches full close position, door reverses to full open.

19
SECTION D: For all operator control types
Adjustment of door travel is done by moving the limit cams on the threaded shaft. The position of the 4 limit switches
are factory adjusted and should not be altered. The limit switches are:
- “Open” limit switch: End of door travel in the fully open position
- “Closed” limit switch: End of door travel in the fully closed position
- “Advanced Open” limit switch: Used for open/close devices or timer to close features.
- “Advanced Closed” Limit switch: Used to prevent reversing device from reversing door when door is
almost fully closed.
To adjust door travel:
1. Open cycle: Depress cam plate and spin “Open” limit cam away from “Open” limit switch to increase door travel
or spin “Open” limit cam towards the “Open” limit switch to decrease door travel. After each adjustment ensure
that cam plate fully engages in slots of both limit nuts.
2. Adjust “Open” limit cam so that door stops at the desired fully open position.
3. Close cycle: Depress cam plate and spin “Close” limit cam away from “Close” limit switch to increase door travel
or spin “Close” limit cam towards the “Close” limit switch to decrease door travel. After each adjustment ensure
that cam plate fully engages in slots of both limit nuts.
4. Adjust “Close” limit cam so that door stops at the desired fully closed position.
