TABLE 3
(below) lists the maximum door opening speeds
specified by ANSI 156.19 for Low - Energy Door Operators.
4630/4640 max. opening speed to 90° is 5 seconds. If weight of
door is unknown, use
TABLE 4
to determine approximate door
weight.

BASIC OPERATION INFORMATION
Note: If fire alarm contacts are activated at any time during
the opening cycle or while in hold open, the 4600 series Door
Operator will override any function and close the door immediately.
All power door functions are stopped until the fire alarm contacts
are deactivated.
When triggered by actuator switch:
1. Controller checks for optional swing-side safety sensor input. If
activated, opening cycle is aborted.
a. If sequential actuator inputs are used then the A-B
SEQUENTIAL DELAY timer is started.
b. Auxiliary and E.S. Relay contacts are triggered.
2. Opening cycle starts after ELECTRIC STRIKE DELAY times
out.
3. Motor & clutch are activated.
a. If sequential actuator inputs are used then the A-B
SEQUENTIAL DELAY output will signal the next operator.
4. Controller monitors the motor during opening cycle for door
obstructions that exceed the present OPENING FORCE
setting. If an obstruction is encountered controller will pause
opening cycle for one second, then attempt to open door again
(SECOND CHANCE feature).
a. Opening cycle resumes until power opening range is
reached or a second obstruction is sensed.
b. Opening door encounters BACKCHECK range of door
closer. A strong BACKCHECK setting will cause controller
to act as though it hit an obstruction, triggering the
SECOND CHANCE feature. Some experimentation with
OPENING FORCE, OPENING SPEED & BACKCHECK
settings may be necessary for applications where wind and/
or air pressure problems occur.
c. Controller goes into HOLD OPEN DELAY mode for preset
amount of time.
d. The controller will maintain the hold open mode as long
as an actuator input signal is present. The HOLD OPEN
DELAY mode timer is reset with each additional actuator
input signal. With each additional sequential actuator input
a sequential output signal is sent.
5. Controller checks for optional push-side safety sensor input. If
activated, the operator will hold door open until sensor de-
activates.
a. Controller releases door for closing cycle. Closing cycle is
controlled by door closer assembly.
COVER INSTALLATION
1. Depending on conduit option used and hand of door, remove
proper knock - outs from operator cover. NOTE: If concealed
conduit option is being used, do not remove conduit knock -
outs.
2. Align cover with operator and guide into position as shown
here in
Fig. 14
. Attach cover to the operator using (2) painted #
8 - 32 x 3/8” flat head machine screws, as shown.
