Threshold setting
Press
or
button to access the setting mode. The device displays the threshold value and the buttons
or
permits to increment or decrement the value. the display blinks during the setting. The adjusted value is automatically
validated after 4 seconds if no button is pressed. The threshold value is then stored in internal non volatile memory and
the message
‘
End
’
appears briefly indicating success of memorizing.
Configuration
Press
+
buttons for more than five seconds to access configuration mode.
1) Input configuration
The device displays the current input type. Pressing
button validates the choice and move to the relay configuration.
Press
button to display the next input type.
The displayed input type choices are:
-
‘
rtd
’
for a platinum PT100 sensor.
-
‘
tcJ
’
for à
J
thermocouple sensor.
-
‘
tcH
’
for à
K
thermocouple sensor.
-
‘
tct
’
for à
T
thermocouple sensor.
2) Relay configuration
The device displays
‘
rEL
’
. Pressing
button provides access to the relay configuration. Pressing
button leaves
the configuration mode and returns to measure mode.
The relay parameters are:
- Threshold,
- Hysteresis,
- The type of detection, high or low.
2.1) Threshold configuration
The device displays the message
‘
thr
’
. Pressing
button provides access to the threshold setting and pressing
but-
ton to switches to the next topic. The device displays the threshold value and the buttons
or
permits to increment
or decrement the value. the display blinks during the setting. The adjusted value is automatically validated after 4 sec-
onds if no button is pressed.
2.2) Hysteresis (dead band) configuration
The device displays the message
‘
db
’
. Pressing
button provides access to the hysteresis setting and pressing
button to switches to the next topic. The device displays the hysteresis value and the buttons
or
permits to incre-
ment or decrement the value. the display blinks during the setting. The adjusted value is automatically validated after 4
seconds if no button is pressed.
2.3) Type of detection
The user can, with this setting, set the direction of the threshold detection.
It works in this manner:
-
High threshold
detection (cooling):
.alarm is activated when temperature goes above threshold,
.alarm is removed when temperature goes below threshold minus hysteresis.
-
low threshold
detection (heating):
.alarm is activated when temperature goes below threshold,
.alarm is removed when temperature goes above threshold plus hysteresis.
