Is the WGC02 still available?

No. The WGC02 is discontinued and is no longer produced. The WGC01 replaces it.

Can WGC01 replace a WGC02 on an existing machine?

On the electrical side yes. Both run on 24 V DC, take the same dual analog sensor input, carry the same six-channel programmable digital I/O and communicate over RS485 Modbus-RTU, so the existing sensors, actuator and wiring normally stay in place. Confirm the panel cut-out dimensions with us before ordering, as the enclosures are not identical.

Is WGC01 better than WGC02?

On the two figures that changed, yes. Response time goes from 4 ms to 2 ms and maximum drive power from 150 W to 240 W. Processor, sensor interface, I/O, communication, supply voltage, environmental range and protection circuits are the same.

Do I need to change the sensors or the actuator?

Normally not. WGC01 drives the same EURDOW actuator range and accepts the same EURDOW edge, center and line sensors. If the actuator draws more than 150 W it was already outside the WGC02 rating, and WGC01 covers up to 240 W.

EURDOW WGC02 Web Guiding Controller

If you have a WGC02 on a machine and need another one, the short answer is that it is no longer produced. The WGC01 replaces it, on the same 24 V supply, the same dual analog sensor input, the same six-channel I/O and the same RS485 Modbus-RTU — with a faster response and more drive power.

This page keeps the original WGC02 specifications so you can confirm what is on your machine, and sets the two controllers side by side so you can see exactly what changes.

WGC02 and WGC01, side by side

Nine of the twelve specifications are identical. Two improved. One is the reason you are reading this page.

Diagnostics	Fault alarm with code display	Limit alarm, fault alarm, self-diagnosis

One thing to check before you order. The electrical interfaces match, so the sensors, actuator and wiring normally stay where they are. The enclosures are not identical, so the panel cut-out may need adjusting. Send us a photo of the installed unit and the panel opening and we will confirm before anything ships.

Original Specification

WGC02 as it was supplied.

Kept here so you can confirm what is actually fitted to your machine before ordering a replacement — the label is often unreadable after a few years in a converting environment.

Before you replace it

Most WGC02 units we are asked to replace are genuinely at end of life, but it is worth ten minutes to be sure.

Display dead, no response

Confirm 24 V DC at the terminal under load rather than open circuit. A failing shared supply on the machine produces the same symptom and is a cheaper fix.

Fault code on screen

The WGC02 reports a code rather than a plain fault. Send us the code and what the machine was doing — several of them point at the sensor or the actuator, not the controller.

Web hunts and will not settle

Usually gain or sensor mounting rather than hardware. Check the sensor sees a clean edge and is square to the web, check the actuator for backlash, then reduce gain.

Actuator does not move

If it moves in manual but not in automatic, the problem is on the sensor side. If it does not move at all, check the actuator connector before the controller.

Correction runs backwards

Sensor channel or actuator direction reversed, normally after a sensor swap or a rewire. A parameter setting, not damage.

Genuinely dead

Then the WGC01 goes in. Same wiring, faster response, more drive power. Ask us for the panel dimensions first.

What goes with it

WGC01 Controller

The direct replacement. Same interfaces, 2 ms response, 240 W drive.
