Temperature Hold Functions; Sensor Control; Analog Output; Relay Output - Fluke Endurance Series User Manual

With these settings the function for the analog input can now be switched via the trigger:
•
Active trigger → background temperatue compensation via the analog input
•
Deactivated trigger → emissivity setting via the analog input

14.5.5 Temperature Hold Functions

For detailed information to the various temperature hold functions along with their resets and timing values, see
section 6.3 Post Processing, page 55.

14.6 Sensor Control

14.6.1 Analog Output

The current output corresponds to the target temperature value.
XO=4 sets the current output range to 4 - 20 mA
H=500 sets the temperature for the top analog output value to 500 (in current scale)
e.g., the top current output value of 20 mA shall represent 500°C
L=0 sets the temperature for the bottom analog output value to 0 (in current scale)
e.g., the bottom current output value of 4 mA shall represent 0°C
Please note a minimum temperature span between "H" and "L" command values.
For testing purposes the output can be forced to provide a constant value using command "O".

14.6.2 Relay Output

The relay output can be triggered by the following alarm sources:
•
target temperature via command SAS=0
•
internal sensor temperature via command SAS=1
The relay output can be set to:
K=0 relay contacts permanently open
K=1 relay contacts permanently closed
K=2 relay contacts triggered by alarm source, N.O. normally open
(normally open: relay contacts are open while in the home position)
K=3 relay contacts triggered by alarm source, N.C. normally closed
(relay contacts are closed while in the home position)

14.7 RS485 Communication

The serial RS485 communication is in 2-wire mode.
For setting the baud rate, the following command must be used.
D=384 sets the baud rate to 38400

14.8 Multidrop Mode

Up to 32 devices can be connected within an RS485 multidrop network, see section 7 RS485, page 60. To direct
a command to one sensor among the 32 possible, it is necessary to "address" a command. Therefore, a 3-digit
number is set prior the command. The 3-digit number is determined between 001 and 032. A unit with the address
000 is a single unit and not in multidrop mode.
XA=024 sets the device to address 24
Changing an address:
(e.g., the address is to be changed from 17 to 24)
