The Diagnostic Menu displays the following parameters:
• Software version release
• Speed Range Setting
• Internal Thermostat reading – Celsius
• Internal Thermostat reading – Fahrenheit
• Motor rpm reading
• Supply Voltage Frequency
• Door Switch status
• External Thermostat status
• Heater Relay status
• Error Code 1 – Speed Sensor
• Error Code 2 – Line Frequency
• Error Code 3 – Power Issue
• Error Code 4 – Motor Off Fault
6.1. Software Release Version – Format: rX.XX
6.2. Fan Speed Range – rn XX (see Section 7.1)
6.3. Thermostat Probe – Pr XX (see Section 7.2)
6.4. Internal Thermostat – ºC (np = no probe)
6.5. Internal Thermostat – ºF (np = no probe)
6.6. Motor RPM – measured speed in rpm
6.7. Supply Voltage – measured frequency in Hz
6.8. Door Switch Status – 0=open, 1=closed
6.9. External T-stat Status – 0=open, 1=closed
6.10. Heater Relay Status – 0=open, 1=closed
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 fre-
quency. 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 compat-
ible 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 set-
ting identified by "rn". Select the correct speed range (see Sec-
tion 7.1) based on the Series/Model. Press "OK" button.
6.11.6. Error Code 6 – Incompatible Speed Range for Mas-
ter/Slave Operation
Er 61 – Status of this error is not available. It only appears when
unit are connected in a Master/Slave 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 Master unit (the unit used
to make setting selections) the Slave unit will display an "Er 61"
and the Slave will ignore the command to protect the control
from damaging the motor.
Solution – Enter the Factory Menu to select the proper Speed
Range (See Sections 7 and 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.
7. Factory Menu – Service Personnel Only
The Factory Menu must be entered from the DIAG header. To
enter into the Factory Menu hold down the right arrow for 5
seconds. DIAG will display when the Diagnostic Menu is avail-
able. From the DIAG display, press and hold the up and down
arrows simultaneously for 10 seconds. FACT will display when
the Factory Menu is available.
Note: When the Factory Menu is accessed it automatically
shut the unit off by changing the Mode to OFF.
The Factory Menu is used to change or reset core settings to
change base functions or resolve Intelliswitch™ errors.
The Factory Menu allows parameters for the following options
to be set:
• Speed Range Setting
• Restore Factory Default Settings
• Reboot Software
• PASScode
• Supply Voltage Frequency
To enter into the Factory Menu from the header press the down
arrow. Use the left & right arrows to change setting values. Use
the OK button select action and return to the User Menu.
7.1. Speed Range: single level
N
rn
0 – 1 – 2 – 3 – 4 – 5 – 6 – 7 – 8 – 9 – 10 -11 – 99
Select the fan speed range from 0 to 11 using the left or right
arrows. The speed range for each unit is located on the unit wir-
ing diagram called out in a box in the Intelliswitch® schematic
by "SPEED rn __".
