INPUT TEST
The INPUT TEST function allows the state of the control board input signals to be examined. The input test menu is common to both versions of the Hot Beverage Merchandiser line and as such contains references to all possible input devices. The state of brewer position index inputs will be visible even if the brewers themselves are not fitted on a particular version.
On entering INPUT TEST, the display will show the device name of the first device in the list and logical state associated with the condition of its input. That is to say the meaning of the state of the input is displayed rather than a simple high or low value. Thus the values displayed for the waste probe are WET or DRY. The screen will dynamically reflect the condition of the input. The keys are used to step through each input in turn. The following input signals can be examined:
| INPUT DEVICE | STATE1 | STATE2 |
| Coffee brewer index | CBREWER HOME | CBREWER NOT HOME |
| CUPS AVAILABLE | CUPS NOT AVAILABLE | |
| CUP DROP IN POS | CUP DROP OUT POS | |
| Dispense arm ‘forward-ready-to-Vend position’ micro switch | IN V POS | NOT IN V POS |
| Dispense arm ‘HOME position’ micro switch | ARM NOT HOME | DISP ARM HOME |
| Boiler level probe | BOILER IS WET | BOILER IS DRY |
| Waste bucket probe | WASTE IS WET | WASTE IS DRY |
| User cup sensor | CUPSNS:NO CUP | CUPSNS: CUP PRES |
| Brewer pressure switch | NO PRESSURE | PRESSURE |
| Jug switch | 0 (Normal) | 1 (jug or free) |
| Free input (J6 pin 13) | OFF | ON |
| Security (J6 pin 10) | OFF | ON |
