tm1 – TIMER
The tm1 reject timer is useful for applications
requiring instantaneous reject action with zero
delay time. Typical applications would be gravity fall
reject mechanism or simple stop alarm conveyor
system.
Sample Size
Small size metal contaminants should be used to
set the timer, the use of large contaminants will
produce errors in the settings. Try to use the
smallest metal sample that can be detected. If this
is not possible use the smallest sample available
and adjust the sensitivity so that the sample gives
an indication of 2 to 3 red bars on the bar graph
display.
Setting Timer type tm1
At this stage the user should be familiar with use of
the control panel and adjusting digital values.
Setting the timer can only be achieved from the
Engineers Mode.

value
7) Press enter twice: display reads:

Type tm1 SET/UPDATED
for five seconds and then returns to main menu
8) Test operation of the reject device to check
tm 1setting is correct.
If no further adjustment is required press Pro Exit
and return to running mode.
Notes:-
a) The reject time is automatically extended in
relation to the size of the metal detected, ie the
smaller the piece the shorter the time. b) If two or
more metal pieces pass through the detector within
the set reject time, the reject time is automatically
extended to ensure rejection of; pieces.
