RS1 and RS2 together. This function defines how

chosen. This requires the contact to be closed for
one second before resetting occurs which prevents
false resetting.

5.5.23 Status output:
5tat oP
The status output of the Timer is an opto isolated
open collector that can be used for transmitting the
status of the Timer to other instruments. It may also
be used for simple control applications.
When the
Status output is
on
the RTx annunciator on the
Timer display is activated.
The status output function contains four sub-
functions,
EnbL

turn
off

Timer state. e.g. if

sub-function and
done
is selected the
5tat off

done
state. Alternatively, the status
output phase may be reversed by selecting the
n
states such as

on
in only one
Timer state, this can be achieved with the following
configuration.
