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).

Press the key below the icon to get to the main menu selections

In this example, I will program the analog output (A1)

to send out 50% (12 mA) when put in HAND mode

to prove if the AO card is working.

Press

Press

to scroll down until Hand Output

is highlighted.

to enter the Hand Output menu and enter 50%. Press to accept this value.

Power down the controller. If the AO signal wires are connected to the controller (TB2 terminals 1 and

2), please disconnect them.

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.

Power the controller back up and see if you now read 12mA. If not, then the AO is faulty and a

replacement front panel assembly (FPA = the entire front door) is needed. Please contact your

distributor Walchem Customer Service 1-508-429-1110 for a replacement FPA.
