CX-33PS Advanced Logic Control Relay & Power Supply Cabinet
INSTALLATION INSTRUCTIONS
LOR Circuit:
A parallel connection is made to the two motor wires running
from the Operator (motor) to its control. If the motor is AC,
then polarity is not an issue. The CX-33 is triggered by the AC
voltage going from high to low.
If the motor is DC, then the wires are polarity sensitive. If
Relay 3 LED doesn’t illuminate when the door is closing, then
just reverse the two terminal connections at the CX-33.
Input 1 is for the N.O. relay contacts of the photo beam. The
beams are typically mounted at the end of guide rails and
designed to reset the LOR in the event anyone should walk
into the swing path when the door is in the closing cycle.
Relay 3 output is to be connected in SERIES with the safety
device and the Safety Circuit of the operator.
Optional Switching Network:
Wire the activating device(s) to DRY 1, DRY 2 or DRY 3
terminals. Wire the outputs as shown to Relays 1 & 2.
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.
It is NOT recommended to add the “Delay-on-activate” (or
nuisance delay) feature in this mode. Once the desired
operation is achieved, proceed to Section 4, (Page 9) for
System Inspection Instructions.
Section 3 K
Low Energy SAM Plus (Mode 10)
This mode combines a Low-Energy Secondary Activation
Module (SAM) with a switching network (aka make/break
relay). Utilizing a door position switch input, this mode
enables or disables a door mounted presence sensor. The
sensor is put into the circuit when a wall switch is pressed
(a Knowing Act). This allows an object or person in the path
of the door to be detected. The door will not close until the
object or person leaves the door swing path. The sensor
remains in the circuit until the door is closed.
When the door is opened manually, the safety sensor is not
in the circuit and the door operator functions as a manual
door closer. A unique feature of the CX-33 is the automatic
reset feature. If a switch has been pressed, but the door
has not opened within 60 seconds (because it is locked, for
instance), the unit resets, reducing wear and tear on the lock
and operator.
In addition, one input and two relays are provided for the
switching network function.
Refer to Diagram 10, (Page 21) for the following connections.
SAM Circuit:
Connect the momentary activating switch(es) to DRY 3 input.
The door mounted sensor connects to DRY 2 input, and the
magnetic contact switch connects to DRY 4 input. The contact
switch circuit must be closed when the door is closed, and
open when the door opens.
Relay 3 output is to be connected to the Activate circuit of the
door operator.
Optional Switching Network:
Wire the activating device(s) to DRY 1 terminals.
Wire the outputs as shown to Relays 1 & 2.
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.
It is NOT recommended to add the “Delay-on-activate” (or
nuisance delay) feature in this mode.
Once the desired operation is achieved, proceed to Section 4,
(Page 9) for System Inspection Instructions.
Section 3 L
Mag Lock with N.O. Fire Alarm (Mode 11)
Commonly seen in hospital corridors, this version of a
switching network (make/break relay) is specifically designed
for doors with mag locks.
A wall switch signals the relay, which unlocks, and opens the
door for an adjustable time. Utilizing the door position switch,
the CX-33 will not re-apply power to the magnetic lock until
the door is fully closed. The relay also provides for a normally
open Fire Alarm input, which when activated, unlocks the
door and disables the wall switch inputs.
Refer to Diagram 11, (Page 22) for the following connections:
Momentary switches connect to DRY 1 and/or WET terminals.
Maintained devices connect to DRY 2 input (optional).
The N.O. Fire Alarm signal is wired to DRY 3 input, and the
Door Position Switch connects to DRY 4 input. The circuit
must be closed when the door is closed, and open when the
door opens.
The magnetic lock connects to the Common and N.C terminals
of Relay 1. The door operator connects to the Common and
N.O. terminals of Relay 2. Relay 3 output is optional.
Once input and output connections are made, program the
unit according to the General Programming Instructions on
page 1, and walk-test the installation. Timing adjustments
may need to be made.
It is NOT recommended to add the “Delay-on-activate” (or
nuisance delay) feature in this mode!
Once the desired operation is achieved, proceed to Section 4,
(Page 9) for System Inspection Instructions.
Section 3 M
Mag Lock with N.C. Fire Alarm (Mode 12)
This mode is identical to Mode 11 (Section 3L) except the Fire
Alarm input is a N.C. circuit (rather than N.O.). See previous
section for wiring and adjustments, & refer to Diagram 12,
(Page 23).
