9.23.7 “Output 1“/
„Temperature OK“ signal
(with time control)
On controllers up to software revision 022,
the switching output at terminals 20+21 was
called "Temperature OK". The more general name
"Output 1" is used as of software revision 100
because this output now also supports other func-
tions.
The "Output 1" signal is available at terminals 20+21 as
a digital control signal.
If time control (timer function) is active, the switching
output at terminals 20+21 ("Output 1") can be parame-
terized in the same way as relay K1. The options for
"Output 1" are specified with step 222 in the Configura-
tion menu as followed:
1. "Off"
2. "When start signal present"
3. "When temperature reached"
4. "While cooling"
5. "End-of-cycle impulse"
6. "Active if Tact = Tset"
7. "Active if Tact = Tset", with latch function
(factory setting)
For a detailed description of these functions, see
section 9.23.6 "Relay K1 (with time control)" on
page 41.
