6.11. Error Codes
The Intelliswitch™ has six error codes, 1 through 6, to help troubleshooting. The status of 1-4 can be observed from the Diagnostic Menu. The format for displaying the error code is the “Er” descriptor and a two digit code. The first digit is the error number and the second digit is the status using international convention. 0 = inactive, 1 = on or active.
6.11.1. Error Code 1 – Speed Sensor
| Er 10 | Prox Sensor or Speed feedback exists |
| Er 11 | NO Prox Sensor or Speed feedback |
Solution – check to see if the proximity sensor (located next to the motor) is connected to the control board and check distance between tip and trigger bar is approximately 1/16 of an inch.
6.11.2. Error Code 2 – Line Frequency
| Er 20 | power supply line frequency exists |
| Er 21 | undetermined supply line frequency |
Solution – The Intelliswitch™ automatically senses line frequency. In the event that it can not determine the proper line frequency, it will run at full speed and flash error. Manually set the line frequency in the FACT menu. See Section 7.5.
6.11.3. Error Code 3 – Zero Cross/Power Issues
| Er 30 | clean power exists |
| Er 31 | poor power exists, electrical noise |
Solution – When the control encounters “noise” in the electrical power supply it will run at full speed and flash error code. There are no internal changes available. Have the electrical system checked for problems.
6.11.4. Error Code 4 – Speed Feedback
| Er 40 | proper motor and sensor operation |
| Er 41 | Motor off but receiving prox/speed sensor feedback |
Solution – this is usually the result of a failing motor control component on board that cannot be serviced. A replacement board is required.
6.11.5. Error Code 5 – Corrupted Memory Setting
| Er 51 | Status of this error is not available. It only appears when there has been an event that has corrupted the settings in memory. When corrupted settings are identified the control will reset all settings (except for Speed Range) back to Factory default values. Because some speed ranges are not compatible with all motors, the proper value cannot be automatically set and therefore requires user input. This is prompted by the scrolling “Set FACt SPEEd” on the display. |
Solution – press the “OK” button. This will open the range setting identified by “rn”. Select the correct speed range (see Section 7.1) based on the Series/Model. Press “OK” button.
6.11.6. Error Code 6 – Incompatible Speed Range for Serial Network (Primary/Secondary) Operation
| Er 61 | Status of this error is not available. It only appears when units are connected in a serially networked configuration that do not have identical Speed Range settings.
If two units are connected without equivalent speed ranges, every time a button is pressed on the Primary unit (the unit used to make setting selections) the Secondary unit will display an “Er 61” and the Secondary will ignore the command to protect the control from damaging the motor. |
Solution – Enter the Factory Menu to select the proper Speed Range (See Section 7 and Section 7.1)
Note: This error does not monitor if the correct speed range has been selected for a Series/Model. Only that two or more units have been connected that do not have equivalent speed ranges.
Note: Once the correct speed ranges are selected and the controls accept commands from one another, the controls should be synchronized by simply cycling through all of the settings on the User Menu using the up or down arrows. None of the settings need to be changed.

8. External Connections
There are four types of external connections available on the Intelliswitch™.
- Door Switch
- Building Management System
- External Thermostat
- Serial Connection
8.1. Auto Mode Activation
When terminals 9 and 10 in the junction box are connected (closed), the Auto, Deluxe, Plus and Programmable Modes are activated. The Intelliswitch™ uses a low 5 volt DC voltage signal to monitor contact closure.
8.1.1. Door Switch (limit switch)
The door or limit switch is used in conjunction with the Auto, Deluxe, Plus and Programmable Modes to signal that the door is open. Connect the door or limit switch to terminals 9 and 10 in the air curtain junction box.
8.1.2. Building Management System
A building management system or dry contact closure can be used to activate the air curtain through the Auto, Deluxe, Plus and Programmable Modes. Connect applicable contacts to terminals 9 and 10 in the air curtain junction box.
8.2. Heat Mode Activation
When terminals 6 and 7 in the junction box are connected (closed), the Heat Mode is activated for all Operating (On, Auto, Deluxe, Plus and Programmable) Modes. The Intelliswitch™ uses a low 5 volt DC voltage signal to monitor contact closure.
If the internal thermostat is left on, the external heat mode will operate in parallel to contact closure, allowing either one to activate the heat. If the internal thermostat is turned off the external heat mode will activate independently to activate the heat.
8.2.1. External Thermostat
An external (remote) thermostat connection can be used to sense temperature independent of the built-in thermostat. Connect thermostat to terminals 6 and 7 in the air curtain junction box.
8.2.2. Building Management System
A building management system or dry contact closure can be used to activate the Heat Mode for all Operating Modes. Connect applicable contacts to terminals 6 and 7 in the air curtain junction box.
8.3. Serial Network Connection (Primary/Secondary) Operation
For Serial Network Operation a serial cable connection must be made between all Intelliswitch™ controls of each air curtain to be linked. Once air curtains are linked, all Menu settings made through any air curtain display or remote control will transfer to all other linked air curtains. Parameter changes made on any linked air curtain will update all other boards “live” upon menu selections.
9. Infra-red Remote Control
The handheld infra-red remote control buttons, layout and operation are the same as that on the Intelliswitch™ air door display (including multiple button presses) with one exception, the Lock Button.
There is no need for multi-button press and hold for lock/unlock activation. The Lock Button will lock/unlock display in one press.
