Control Box Installation Instructions

For closer information see closer installation instruction sheet

Installation

  • 1a Locate box on interior of building within 50 tubing feet of the farthest door to be controlled. Box must be in a clean, dry, well ventilated place where temperatures do not exceed 120°F or fall below 35°F.
  • 1b Mount box to a structurally sound surface using screws provided as shown on page 2 with air fittings on left side as shown. Do not mount box upside down or on a horizontal plane.
  • 1c Refer to instructions packed with actuators and connect leads to terminals 5 through 10 as required.
  • 1d Connect unpowered 120V AC input to terminals 3, 4, and ground screw. (Line side to terminal 3, neutral side to terminal 4 and ground wire to ground screw.) If door control is on a fire door, 120V AC input must be interrupted by the fire alarm panel when in alarm. When dry auxiliary fire alarm contacts are used, remove shunt from terminals 1 and 2 and connect to dry contacts of fire detector or alarm panel. Terminals 1 and 2 are in series with line side of 120V input.
  • 1e Turn on power. Air valves and compressor will operate one cycle when power is applied.
  • 1f Air pressure output has been preset at factory. If more air pressure is required to adequately open door, regulate air adjustment valve on pump, as shown on page 3.

  • 1g Adjust time delay to keep air valve energized by turning adjustment wheel on timer modules "A" & "B" (CW to increase - CCW to decrease). The LED (light) on the timer module indicates the valve is energized. The time can be adjusted from 0-30 seconds. 10 seconds is a "normal" delay.
  • L NOTICE: Timer Module "A" and "B" must operate longer than Timer Module "P".
  • 1h Adjust timer module "P" to keep compressor activated for the necessary amount of time to open the door. This can be done by rotating the adjusting wheel. (CW to increase - CCW to decrease). The LED (light) on the timer module indicates the compressor is energized. The compressor should not run more than 1-3 seconds longer than the time required to open the door.
  • 1i When using sequential operation, adjust dual timer module "S" for desired delay between door operation. (CW to increase delay; CCW to decrease delay.) Top timer delays "A" to "B" operation; the bottom timer delays "B" to "A" operation.
  • 1j Test actuators to insure wiring and tubing are properly connected.

ACAUTION

DO NOT MOUNT BOX UPSIDE DOWN OR IN HORIZONTAL POSITION. LOCATE WHERE TEMPERATURES DO NOT EXCEED 120°F OR FALL BELOW 35°F

ACAUTION

COMPONECTS INSIDE CONTROL BOX WILL BE HOT TO TOUCH UNDER NORMAL OPERATION. ALLOW BOX TO COOL DOWN BEFORE MAKING ADJUSTMENTS.

HAZARDOUS VOLTAGE CAN SHOCK AND CAUSE SEVERE INJURY

Disconnect power before making any electrical connections or performing maintenance.

INSTALL BOX WITH SIX TAPCON - CONCRETE SCREWS 3/16 x 1 1/4 DRILL 5/32 HOLE 1 1/4 DEEP WITH CARBIDE TIPPED CONCRETE DRILL BIT

AIR FILTER SHOULD BE INSPECTED EVERY SIX MONTHS. IF FILTER IS DAMAGED, CONTACT LCN FOR REPLACEMENT.

ELECTRICAL DATA

INPUT = 120V AC @ 5 AMPS POWER CONSUMPTION 600 WATTS OUTPUT IS 12V DC (250 mA MAX. LOAD)

A DANGER

CONTROL BOX MUST BE CONNECTED TO EARTH GROUND

* REMOVE THIS SHUNT ONLY WHEN CONNECTING TO NORMALLY CLOSED FIRE ALARMS CONTACTS

Air Pressure Adjustment

  • 1a Loosen lock nut. (A)
  • 1b Turn outer valve (B) to regulate air pressure.
  • 1c Tighten lock nut.

Installation Troubleshooting Chart

Symptom Possible Cause Suggested Remedy
No Power Opening No power to control box / blown fuse Verify 120VAC 60HZ power is present
at terminals 3 & 4 on control box
terminal strip. Check fuse. Replace only
with 5 amp (3AG type) fuse.
Actuator(s) not connected properly Be sure a timer module board is firmly
in place in "A". "B" & "P" slots. Timer
"S" must be in place for sequential
operation. Operate actuator(s). LED on
timer module should light when actuator
is used. The LED on timer "P" should
light whenever "A" or "B" is lit. If not,
momentarily short actuator terminals
6 & 10 and 8 & 10 in the control box.
If LED lights, check wiring to actuators
for an open circuit. If it does not light,
check for voltage at terminals 9 &
10. Voltage should read from 11.75
to 13.25V DC. If there is no reading,
disconnect leads from terminals 9 & 10.
Short actuator terminals. If LED lights,
check for short circuit in actuators.
Fire alarm system causing open circuit
on terminals 1 & 2
Shunt terminals 1 & 2 with power off.
Restore power. If control operates when
actuator terminals in the control box are
shorted, an open circuit exist in wiring
to fire alarm. When Auto-Equalizer is
not used with fire alarms, terminals 1 &
2 must be permanently shorted with a
shunt.
No input to Auto-Equalizer operator IMPORTANT! When Auto-Equalizer
is connected to fire alarm, make sure
shunt is removed from terminals 1 &
2. Terminals 1 & 2 are one leg of 120V
line.
Disconnect tubing from Auto-Equalizer
operator. Try actuator and verify that
air is coming out of tubing. If not, trace
tubing to control box, checking for
breaks or kinks in air line.
Air lines obstructed with dirt or ice. Clean or thaw lines and reroute if
necessary. Eliminate dips near cold
zones.
Air valves not working Make sure air valve leads are plugged
into main board. (Be sure valves in
system are plugged into connectors "A"
& "B".)
Compressor not working Make sure compressor leads are
plugged into main board. (Be sure
compressor is plugged into connector
"P").
Does not open or fully open Control box exhaust restricted. Exhaust muffler may be clogged by
dirty air or accidental painting. Clean in
alcohol or mineral spirits.
Opens too slow or not at all Inlet filter clogged Replace filter element (Contact LCN for
replacement)
Symptom Possible Cause Suggested Remedy
Power opening will not time out. Scanner maintaining signal to control
box.
Make sure lenses are clean and there
are no obstructions in front of scanner.
Model 909 or 939 proximity scanner
may "see" an opposite wall. Adjust
range as described earlier.
Switch circuit maintaining contact. Check for short circuit or error in wiring
to switch or scanner.
Air valve blocked open with
contaminant.
Cycle valve several times by
momentarily shorting actuators in the
control box. This should clear valve.
Power opening timing out too soon. Air compressor needs readjustment.
Timer cards not set properly
See page 2 for regulation instructions.
Set timer cards "A" & "B" for Max.
time. Set timer card "P" for Min. time.
Slowly increase card "P" until "time
out" is 1-3 seconds after door is fully
open. Decrease timer card "A" & "B"
to achieve desired time delay before
closing. (Make sure "P" times out
before "A" & "B".)
