Features and Functions
Magic-Touch™
: A feature that allows the door to be actuated by a slight manual movement of the door-without the need for
an approach sensor. The MC521 PRO control box controls the Magic-Touch hold-open time delay. Magic-Touch can be used with
press plates or a radio control system, providing the system with two separate time delays. Magic-Touch is not recommended for
use with a dual door system using Swing Guard T. With dual door systems, Magic-Touch can be selected to open doors independently
only.
Reverse On Obstruction
: A reverse-on-obstruction feature causes the door to reverse motion if an obstruction is met during
door opening or closing. It does not however reverse on obstruction while opening until the activation sensor and safety sensor
stop detecting.
Safety Check
:
This feature monitors the safety signal activation on every open cycle. If a safety carpet or overhead safety sensor
fails “open” or can no longer detect a pedestrian, the door stays open for 12 seconds to indicate that there is a problem.
Emergency Breakout:
Disconnects power to the motor when the door is manually pushed in the emergency-out direction. The
operator then automatically resets and power is resumed.
2S Logic
:
Used in trained-traffic applications and is not compatible with sensors. Allows door to open when switch is pushed and
door to close when the next sequential switch is pushed. 2S can be used with a safety sensor.
Low- and High-Energy Operation
: Allows selection of low-speed range (low-energy applications) or high-speed range (full-
energy and all dual-operator applications).
Safety Logic
: Allows the selection of monitored or non-monitored sensors being used.
Single- or Dual-Door Selection
: Allows selection of single- or dual-door operation.
Opening Speed Adjustment
: Permits adjustment of door opening speed.
Closing Speed Adjustment
: On Magic-Force operators, a dual-adjustment closing speed control with two rheostats permits
independent adjustment of door closing speed and closing check speed. On Magic-Swing operators, provisions are provided for
the installation of an optional single-adjustment closing speed control.
Open Check Speed Adjustment
: Permits adjustment of door open check speed.
Torque Adjustment
: Allows adjustment of the door opening force. Open torque, check torque, and stall torque are independent adjustments.
Stall Logic
: Used with a door-mounted sensor system to stop door motion when a pedestrian or object is present.
One-Piece Switch Module
: On Magic-Force operators, the individual breakout, breakout status, close check, and auxiliary
switches have been replaced with a single one-piece switch module.
No Reverse on Obstruction
: Used in Low Energy applications and only while closing. When this option is set to True, then if the
door is obstructed before reaching full closed the door shall “rest” on the object impeding the door motion. The purpose is to
prevent manual door users from being subjected to an obstruction recycle from a previous user push plate activation.
Operate Delay
: Delays the motion of each panel after the operate signal is received. This is useful with pairs of doors where one
panel needs to open before the other.
Lock Logic
: Can be set for a fail safe or fail secure lock/electric strike.
Lock Delay
: Skipped if Door Position Switch is active. Will delay door motion to give a lock time to disengage up to 5 sec. in 0.1
sec intervals.
Manual Mode Sensor Overide
: Can not be used with “Magic Touch”. When set to “On” the door sensors will only be activated
when a push plate or other knowing act activation signal is used. This allows the door to be used as a manual door and will not
power open when pushed. When tuning Swing Guard T, this must be set to off. After Swing Guard T is tuned, this can be then
turned on.
Open Check Boost
: This parameter controls the transition between braking and check speed.
Off Mode
: Set off mode to 01, door closes with sensors active. Function switch must be OFF for door to close.
Unlock Time
: Time that electric strike is unlocked. Time starts when door begins to open. Total time that the electric strike is
unlocked is the lock delay plus the unlock time.
