W100 and W600 Analog Output Card Troubleshooting
This document is a guide for troubleshooting the analog output(AO) card if you are measuring 0mA as
the value of the analog output signal.
Controller Model
To determine if your controller has the analog output card installed, for the W100 controller, the model
number must contain an "A" in the Analog Output block shown below. The analog output option can
only be factory installed for the W100 controllers, it is not field upgradeable.
For the W600 controller, there are 2 ways to determine if the controller has the analog output card. The
model number must contain an "A" in the Analog Outputs block shown below.
Or, the analog output card may have been installed in the field, and therefore the model number will
not reflect that it is installed. So, open the front door of the controller, and visually inspect the back of
the front door. If the analog output card is installed it will be located as shown below. It is a single card,
but can output 2 analog signals (dual analog output option).

- Page 5 W100 and W600 Analog Output Card Troubleshooting Connect your multimeter as shown below. Then power up the controller If you do not read 12mA (approximately), then power down the controller. Please make sure the grey ribbon cable is installed with the red stripe on the bottom (as shown above) and the ribbon cable is securely seated on both ends.
