GENERAL DESCRIPTION
Intended Use
This manual provides installaon instrucons, wiring instrucons, and tune-in instrucons for the MC521 Pro
Controller. It includes instrucons for Dura-Glide™ 2000/3000, 5200/5300, Dura-Guard™, Dura-Storm™, and Dura-
Max™ 5400-Series, Automac Slide door systems.
On Dura-Glide sliding doors, the MC521 Pro Controller replaces the MC521 or both the microprocessor control
box and the interface board on older models. The door acvaon devices (SU-100 moon sensors, carpets, push
plates, etc.), lock, funcon switch, doorway holding beams, and door posion switches previously connected to the
interface board must be connected to the MC521 Pro Controller.
Aachment 1 illustrates the MC521 Pro Controller controls and indicators. Aachment 2 illustrates system wiring
for Dura-Glide series sliders.
Applicability
This manual is applicable to the Dura-Glide series sliding doors used on Dura-Glide™ 2000/3000, 5200/5300,
Dura-Guard™, Dura-Storm™, and Dura-Max™ 5400-Series, Automac Slide door systems. Instrucons for

NOTE: This manual covers new door installaons in which the MC521 Pro is factory-installed and wired.
WIRING INSTRUCTIONS
Evaluating Power Requirements
• ENSURE power source is a dedicated 115 VAC, 50/60 Hz source with 20A circuit rang. If four operators are
used, the source should have a 30A rang.
• ENSURE no more than four operators will be connected to one circuit.
• ENSURE power source is not shared with other equipment, i.e., cash registers, EAS systems, or other electro-
magnec interference generators.

Connecting Main Power Wiring
Warning: To prevent injury to personnel, incoming electrical power to the header must be deenergized before
connecng electrical service to the control box.
Warning: All electrical wiring must conform to Naonal Electrical Code Requirements.
1. DEENERGIZE incoming electrical power to header.
2. Refer to Aachment 2, and, using wire nuts, CONNECT incoming line, neutral, and ground wires
to the controller power harness.
3. IF adhesive wire clamps will be used, DEGREASE metal surfaces on inside of header cover
where clamps will mount.
4. SECURE wiring to top of the header track tube, and ENSURE the following:
• All wires are clear of belts and belt brackets.
• Header cover opens and closes without interference.
Connecting Accessories (As Applicable)
Refer to Aachments 2 and 3, and CONNECT any of the following subsystems to the MC521 Pro Controller:
• Funcon switch (rotary, rocker and “POWER” switch wiring)
• Stanguard threshold sensor
• Doorway holding beam
• Breakout switch
• Solenoid lock
• SU-100 moon sensor(s) wiring (refer to Stanley Document #203957)
• OA-203C presence sensor(s) wiring
• Push plate wiring
• Door posion switch closed contact (with door closed)
• Stanvision
TUNE-IN INSTRUCTIONS
Warning: The door path must be free of objects and remain clear unl the First Install Sequence (FIS) is complete.
During this sequence the sensors are inacve and the door has no SAFETY. To stop the door, turn power off or put
the doors into breakout.
NOTE:
1. Tune In: The MC521 Pro Controller can be tuned-in using a handheld device or using the pushbuon switches
located on the controller. Tune-in using a handheld device is the preferred method.
2. Status Codes: During normal operaon, the digital display indicates status codes. The “UP” and “DOWN” push-
buon switches can be used to enter and display data values. The user interface values are shown in Tables 2
through 4.

or in part without the express written permission of Stanley is prohibited.
3. Solenoid Lock: If a solenoid lock is installed with no lock circuit board (new style), set Lock Logic to the actual
lock type (Fail Safe or Fail Secure). If a Fail Safe or Fail Secure Lock is being installed with a lock circuit board
(old style), the Lock Logic must be set to Fail Secure.
4. Handing: Manually open door nong rotaon of belt pulleys. If counter clockwise (CCW) use right hand during
FIS. If clockwise (CW) use le hand during FIS. See gure below.
5. FIS: The rst installaon sequence (FIS) is used to perform the inial conguraon. Upon compleon of FIS,
all setup parameters are stored in non-volale memory. Subsequent power cycles will reload the congura-
on parameters that were congured during FIS.
6. Decimal points on digital display are encoder 1 signals.
7. Aer changing values, the values must be saved in EEPROM by cycling the door to full open.

NOTE:
1. To change the INDEX:
Hold ENTER switch while pressing UP or DOWN to get to desired INDEX.
2. To change a VALUE:
Unlock the keypad by seng index 99 to value 00.
Aer the desired INDEX is selected, release ENTER and within 2.5 seconds press UP or DOWN to get the
desired VALUE. (If the UP or DOWN buons are not pressed within 2.5 seconds of releasing the ENTER buon,
the display will change from the VALUE back to the STATUS.)
3. To display STATUS CODE:
A few seconds aer the VALUE is selected, the display indicates the STATUS CODE.
4. To show the INDEX and VALUE.
To show the INDEX, hold ENTER. Once ENTER is released the display will show the VALUE of that INDEX.
5. Read the descripons enrely before performing each step. Check the INDEX and VALUE aer each step.
6. To STORE CHANGES in permanent memory:
Cycling door open one me will store changes.
7. To LOCK keypad:
Lock keypad by seng index 99 to value 01 or by turning power OFF and then ON.
8. To ACCESS the door cycle counter funcon:
a. Ensure that the keypad is locked by seng index 99 to 01.
b. Ensure that the index is set to any index but 99.
c. Press the up or down key to access the door cycle counter.
The display will show “dc” followed by four pairs of digits, followed by “dc”.
Example: If the Door count was 12345678 cycles the controller will display “dc” “12” “34” “56” “78” “dc”.
