The exact form of the display varies with system configuration. If a variable speed
conveyor is being used all timer values apart from reject time will be displayed as a
number of tacho pulses (pul). If the system has no photocell then photocell delay
time and alarm time have no meaning, so they will not be displayed.
The way timers work and how to set them up is explained in the subsection entitled
‘timer setup’.
The next screen shows the systemchek time
(only if configured).
Syschek time 5.00s
The next screen shows the NOISE TEST option.

The next screen shows the test-tacho function
(only if tacho is configured).
The test-tacho function allows you to view the tacho sensor pulses on a variable
speed conveyor system. The conveyor must be switched ON for this display to show
