display will still indicate that it is ‘ON’.This prevents damage to the motors.
3. When a different output is selected, or the sub-program exited, the previous
output is automatically switched ‘OFF’.
Note: It is not possible to test the heater using the output test sub-program. Serious
damage may occur if there is insufficient water in the heater tank when the
heater is turned on.
4. Input Test Sub-Program
This sub-program enables the engineer to individually test each of the input lines.
1. The operation of the input sub-program is similar to the output test sub-program
except that the display shows the name of the input and the caption indicates its’
current state:
2. As the state of the input changes, so does the caption on the second line. There
is a delay of approximately three-quarters of a second before the display caption
changes to ensure that any rapid changes can be seen.
5. Keypad Test Sub-Program
The keypad test sub-program enables the engineer to test each key on the keypad to
ensure that it is operating correctly.
1. Whenever a key is pressed, the name of that key will be displayed on the LCD.
Because the access key was pressed to enter the sub-program, on entry to this
sub-program the LCD will display:
2. For numerical keys, the number will be displayed, such as “1 key” or “2 key”. For
other keys, the name of the key will be displayed, such as “Up” or “Down”.
3. To exit from this sub-program into the engineer program, press the blank key.
6. Initialise Sub-Program
The initialise sub-program enables the engineer to return all the parameters to their
factory settings.
