| Check the wiring to the unit from the mains supply | |
|
| then check the following: | |
|
| Fuse and fuse rating | |
|
| Voltage and voltage setting | |
|
| (See Section 2.2 & 2.3 of this chapter) | |
|
| If none of these checks locate the problem and the | |
|
| correct mains supply voltage is present at the input | |
|
| board terminals then a circuit fault exists and | |
|
| replacement of the faulty input board is required. | |
