Relay K1 function
The energizing behavior of relay K1 can be
configured as follows:
Time control OFF:
• K1 is not activated
Relay K1 OFF
• K1 is energized if the "Temperature OK" output
is active
Relay K1 active if Tact =
Tset
Time control ON:
• K1 is not activated
Relay K1 OFF
• K1 is energized if the start signal is present. The
relay is deenergized at the end of the cooling
phase.
Relay K1 active when
START signal present
• K1 is energized if the actual value reaches 95%
of the set point. The relay is deenergized at the
end of the cooling phase.
Relay K1 active when
temperature reached
• K1 is energized at the end of the heating phase
and deenergized again at the end of the cooling
phase.
(This setting is possible as of SW revision 010)
Relay K1 active during
cooling phase
• K1 is energized for up to 0.5 seconds at the end
of the cooling phase (momentary impulse). The
length of the momentary impulse can be
shortened by applying the start signal (during
the impulse).
Relay K1 generates end-
of-cycle impulse

Cycles
The number of heating impulses (not manual
impulses) is counted and displayed with this menu
step. The counter can be reset either by pressing
the "ENTER" key or by restoring the factory
settings.
Reset with "ENTER" key

Alarm relay
This menu step permits the switching
characteristics of the alarm relay to be configured.
• Normal: The alarm relay output (terminals 5+6)
operates as an NO contact in the event of an
alarm.
Normal
• Inverse: The alarm relay output (terminals 5+6)
operates as an NC contact in the event of an
alarm.

Measuring impulse
length
The length of the measuring impulse can be
changed here. This function is only available with a
few special applications (MOD 1).
1.7…3.0ms

Analog output
This menu step determines whether the current
actual value or a 10V reference voltage is output at
the actual value output (terminal 24).
(This setting is possible as of SW revision 017)
