Frequently Asked Questions About the ES-500 Controller and 
Quad Systems, LLC.  EZ-7000 Operators


Q. Can the Access Automation operator be used with a Horton control?

A.  Yes, in most cases the EZ-7000 operator can be used with the Horton C4160-1, C4160-2, C4190, or C7160-3 controls.  An adapter harness would be required to allow the EZ-7000 to plug into the Horton control.  The harness would have the proper connectors on each end and would also include the brown wire for the open check microswitch, which Horton's C7160-3 control requires (Access Automation control does NOT require this connection, so it is not present in the current operator wiring harness). 

Q. Can our control be used with a Horton operator?

A.  Yes, the ES-500 can be used with the Horton S7000 or S4000 operator.  An Adapter harness (Access P.N. A600-0011-02) is required and includes detailed installation instructions.

Q. How do I easily adjust the cams?

A. Place switch on "Hold-Open" (=) position and let the door open to the full open position. Loosen the small Allen head screws on the outside cam (switch with 2 wires). Rotate the cam untill the switch is on the flat part of the cam and tighten screw. Place switch in the "Off" (o) position and let the door close completly.  Loosen the small Allen head screws on the inside cam (switch with 3 wires). Rotate the cam untill the switch is on the flat part of the cam and tighten screw.

Q. I need a motion sensor (or a door mounted approach sensor) that is disabled when the door is fully closed--that is, I only want it to function as a recycle and hold open device for additional safety.  It must be ignored when the door is closed. How can I make this possible?

A.  This feature is supported beginning in Versions 1.02/1.03.  An auxiliary harness (Close Monitor harness, Access P.N. A600-0008-01) will be required.  Set the AF parameter to 2*.  Wire the additional sensor's output contact to the red and black wires of the auxiliary harness.

Q. How can I install a door mounted swing side sensor that slow/stops the door if a pedestrian is detected as the door  is opening?

A.  A door mounted swing side sensor may be installed with the use of a Safety harness (Access P.N. A600-0007-01).  Wire the sensor's output contact to the green and black wires (Stop-N-Seek input) of the Safety harness.

Q. How does a safety mat function?

A. A safety mat will have two wires which will be connected to the black and wire wires of the Safety harness (Access P.N. A600-007-01). If someone is standing on the mat, the switch or sensor will not open the door. If someone opens the door and stands on the mat, the door will not close. After the person steps off the mat the ES-500 will start the "HO" cycle then close.


Q. I am using the operator in a high energy mode. How can I acquire support for a safety beam per ANSI 156.10?

A. 
Although Access Automation, Inc. does not recommend the use of this operator and/or control in a high energy mode, this feature is supported beginning in Versions 1.02/1.03. An auxiliary harness (Close Monitor harness, Access P.N. A600-0008-01) will be required.  Set the AF parameter to 3*.  Wire the safety beam's output contact to the red and black wires of the auxiliary harness.  A beam break will prevent the door from opening if it's closed, prevent it from closing if it's open, slow the door to seek speed if it's opening, and will immediately cancel the lockout delay and re-engage the safety sensor if the door is closing.

Q. What transient filter is built into the control?

A. The control has the industry standard metal oxide varistor (MOV) surge absorber built in. It is rated for 150VAC continuous, 20 joules, and is located downstream of the slow blow fuse. Short overvoltage conditions are typically absorbed by the MOV with no control damage, while prolonged ones (such as accidental connection to the wrong supply voltage) will normally blow the fuse.

Q. Is there any kind of gate to kill spikes?

A. The MOV discussed above would be considered the "gate" that kills spikes. There is also a part called a 'Surge Limiter' on the control. Its function is to reduce the initial surge when the control is powered up, prolonging the life of certain components on the control.
