Operating instructions
6.2 Switching threshold OUT 1
OUT1 changes its switching status when the configured upper and lower thresh-
olds [d1. S P, d1. r P] are exceeded. The source d1. S defines the signal at
the output Out1.
Two sources are available:
• Two-colour mode: [d1] → [d1. S ] = QUot.
• One-colour mode: [d1] → [d1. S ]= SpEc.
First set the upper temperature value of the switching point [d1. S P]. The
temperature can be defined in °C or °F according to the unit setting. Then set
the lower threshold [d1. r P]. When you adjust the upper threshold [d1. S P]
the lower threshold [d1. r P] will change accordingly. The span remains the
same. If [d1. S P]. is lowered to a value where the span cannot be maintained
(as [d1. r P] would then fall below its minimum value), the [d1. r P] is kept with
its minimum value.
If [d1. S P] subsequently increases again, [d1. r P] also immediately increas-
es. The minimum distance between [d1. S P] and [d1. r P] is 2 K.
6.3 Output signal
The following switching functions can be selected:
• Normally open contact: [d1] → [d1. F n]= no (normally open)
• Normally closed contact: [d1] → [d1. F n]= nc (normally closed)
6.4 Upper threshold delay
Once the sensor has detected a temperature which exceeds the switching threshold
[d1. S P] the time delay [d1. d S] starts running. When this delay period has
elapsed, the output OUT1 activates switching. This status is maintained until the low-
er threshold [d1. r P] is violated. If this occurs before the time delay has elapsed,
the delay will reset. This function can be used, for example, to suppress spurious
impulse signals at the output.
• Upper threshold delay: [d1] → [d1. d S] = 0...10 sec.
