Fault Indicators

BOARD FAULTS Tab:

This tab shows hardware faults that could occur. If one of these faults occurs there may be a problem with the control board hardware
or with the LCD Display and buttons.

NOTE: If a Board Fault occurs, try cycling the power to the heat pump. Turn the power off for 10 seconds and then back on

again. If the fault persists then there is most likely a problem with the hardware and the board will need to be

replaced.

Digital Inputs:

A failure has occurred and the Control Board may no longer respond to the digital input signals.

Digital Outputs:

A failure has occurred and the digital outputs may no longer work properly.

PWM Outputs:

A failure has occurred and the PWM / 0-10VDC outputs may no longer work properly.

Analog to Digital:

A failure has occurred and the data from the A to D converter may be corrupt resulting in erratic data values.

Real Time Clock:

A failure has occurred Control Board time and date may no longer be valid, all time stamped data may be corrupt.

Flash Memory:

A failure has occurred stored data may be corrupt. It may be possible to correct this by using the menu item

Tools—Reset to Factory Defaults

. If this clears the fault then the system configuration will have to be setup again.

Menu Buttons:

A failure has occurred and the Control board may no longer respond to menu button keypresses. Try turning off the

power, disconnecting and reconnecting the cable between the LDC Display board and the Control Board and then

turning the power back on again. If this does not work then either the LDC Display board, the cable or the driver

section of the Control Board may be faulty.

LCD Display:

A failure has occurred and display may show erratic data, no data or may not turn on at all. Try turning off the

power, disconnecting and reconnecting the cable between the LDC Display board and the Control Board and then

turning the power back on again. If this does not work then either the LDC Display board, the cable or the driver

section of the Control Board may be faulty.
