5. MEASURED VALUES / MAX. MEASURING RANGE:
The dominant value of the appropriate quantity is displayed in this field. For the factory configuration,
the measured values may fall between the measuring ranges shown below.
*
)
Equals Td above 0 °C
(32 °F)
The measurement ranges indicated above can be set to individual requirements using the EE-PCS.
MIN; MAX:
see point “MIN/MAX Function”, see
chapter 7.2 “Display Module (Option D2)”
CALIB LOW; CALIB HIGH: indicates the low or high humidity/temperature calibration point.
REL1 / REL2:
status relay 1/ relay 2
"ERROR 01....06":
see
chapter 10.4 “Self Diagnosis and Error Messages”
6. STATUS LINE:
8 Optional Modules
The optional modules are mounted in the lower part. For this reason, only one optional module can be
selected at a time.
8.1 ARC-Module (Option AM1)
The additional circuit board located in the lower part of the EE33
enclosure offers the possibiliy to start the ARC heating function
with external signal.
During the heating process the orange LED D3 flashes at the
main printed circuit board. At the ARC module the red LED
"heating" flashes and the relay contact (terminal "output") is
closed.
General information on the ARC function see chapter 4.1.2.
Heating process and trigger parameters can be set and changed
with the EE-PCS.
