and the control will switch to hold open voltage. After a brief delay, the display will switch to SS
(Seek Speed) and the door will creep the rest of the way open, after which normal operation will be
restored. Set the seek speed just high enough to insure that the door creeps open following an
obstruction response timeout.
Note: If the LIMIT adjustment is turned up too far, it may not be possible to get the
obstruction response.
1.5 Actuating & Accessory Wiring
Remove power from the control. Wire the actuating device(s) to ACT connector CN2 as shown in
the wiring diagram. Note that total accessory device current draw should be limited to 0.5A or less.
A radio receiver may be wired directly into CN2, or for easier installation, an optional dedicated
harness may be plugged into RADIO connector CN3 and wired to the receiver.
The remaining connectors are for optional features and are normally unused in low energy
installations. If they are used, wire them as shown in the wiring diagram.
The control directly supports the use of automatic locks of either the mortise or magnetic type. An
optional lock harness must be obtained from Quad Systems. If a lock is to be used, wire it to the
lock harness as shown in the diagram. Typically, the normally closed relay contact is used with
magnetic locks, and the normally open contact for mortise strikes. Be sure to adjust lock parameters
LL and UL as shown in Section 1.7, Parameter List, before attempting operation with a lock. Do not
attempt to power the lock from the control unless the total accessory current draw, including
lock, is 0.5A or less.
After all other devices are wired, power the control back up and check for proper operation. The
green ACT (ACTuate) indicator should light whenever an external actuating device (including the
radio receiver) triggers the door to open. The Red SAF (SAFety) or yellow SNS (Stop-N-Seek)
indicators should light if any of the optional safety devices are active. If any auxiliary switches or
devices are used (see the AF parameter description below), the yellow AUX (AUXiliary) indicator
should light whenever they are triggered.
1.6 Display Codes
During normal operation, the ES500 control displays its current status via the display as follows:
Id Idle, awaiting open command
SA SAfety device active, door prohibited from opening
OS Opening door at Open Speed
OC Opening door at Open Check speed
HO Holding Open
OP Manual Opening detected (with PG turned off)
CL CLosing door, with speed set by close speed adjustment
LC Closing door at Latch Check speed, latch check delay running
SS Opening door at Seek Speed (following obstruction)
Ob Obstruction detected, door stalled**
d1 Time delay 1 in use (delay for normal actuating devices)*
d2 Time delay 2 in use (delay for push and go actuation)*
d3 Time delay 3 in use (delay for touch-stop recycle)*
* These codes flash briefly when the operator switches from open speed to open check to indicate
the current time delay in use.
** The obstruction display results from either a door jam condition during opening, or from triggering
