Operating instructions
The parameter [
DirT
] dirt alert should be set to a signal intensity of
0.5 x. The pyrometer will stop to calculate the ratio temperature when the
disconnection threshold [
q
] → [
q.LiN
].
The current signal strength can be displayed with parameter Q signal
strength [
q
] → [
q.Si6
].
6.10 Sync-pulse
With active memory function
DTD
, a sync pulse is generated when the threshold
is violated. Further details are given in chapter 13.4).
6.11 Inner device temperature
If the internal temperature of 75 °C is exceeded, the switching mode of switching
output OUT2 changes according to its configuration. When the internal temperature
is < 70 °C, the switching output OUT 2 switches back to its original state.
6.12 Output signal
The following switching functions can be selected for dirt alert, signal strength and
inner device temperature:
• Normally open contact [
d2
] → [
d2.Fn
] =
no
(normally open)
• Normally closed contact [
d2
] → [
d2.Fn
] =
nc
(normally closed)
6.13 Upper threshold delay
Once the sensor has detected a temperature which exceeds the switching threshold
[
d2.SP
] the time delay [
d2.dS
] starts running. When this delay period has
elapsed, the output OUT1 activates switching. This status is maintained until the low-
er threshold [
d2.rP
] 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: [
d2
] → [
d2.dS
] = 0...10.0 sec.
