6. Maintenance

6.1 Filter Clean up

The filter needs to be cleaned annually. A dirty filter causes damage to the controller.

6.2 How to Change Probe Fuses

The fuse on the probe PCB (SH2-C001) needs to be replaced when [Probe Fuse Blown Up]

message comes up. Use a quick-acting fuse (2A �6.3).

However, changing fuses itself doesn't solve the problem. Identify the causes of the burned out

fuse and repair it accordingly.

i. Turn the breaker off on the controller and remove the panel (picture below left).

ii. The picture below at left shows the front view of the controller. Using this picture as a

guide, remove the probe PCB that contains the burned out fuse. There is a maximum

amount of ten PCBs on a controller and one PCB contains fuses for four circuits. PCBs are

placed side by side from #1 to #10 (refer the picture below left). Probe PCBs are placed first

and then the manifold PCB.

iii. The fuses are placed F1, F2, F3, and F4 from left to right (refer the picture below at right).

Locate the burned out fuse and replace it.

Ex.) If the zone 6 on VMC8VN4 Controller is suspected for the burned out fuse, change F2 on

#2.

6.3 How to Change Common Fuses

The incorrect wiring and connection or damaged

heater etc. may cause the common fuses to burn

out. This will display [Probe Heater Burned

Out] message.

Replace the burned out fuse with a fast-acting

fuse (10A, �6.3).

i. Turn the breaker off on the controller

and remove the panel.

ii. The common fuses are located on the

output PCB (marked with� on the

6.4 How to Change Manifold Fuses

The burned out manifold fuse needs to be replaced. Use a quick-acting fuse (20A �10.3).

Identify the causes of the burned out fuse and repair it accordingly.

i. Turn the breaker off on the controller and remove the panel (picture below left).

ii. The picture below shows the top view of the controller. Using this picture as a guide,

replace the burned out fuse.

Each zone contains two fuses. Use an ohmmeter to determine which fuse is burned out.

Ex.) If the manifold zone 2 is suspected for burned out fuse, the 3rd fuse and 4th fuse on the

picture below need to be tested.
