4.9 Limit switches with switching output
Two independent working limit switches can be adjusted on this device.
4.9.1 Limit switches representation in % of output
Voltage output Current output
actual measuring value
SIG 6.05V
30.4% 50.4%
Limit switch 1 Limit switch 2
actual measuring value
SIG 6.05mA
30.4% 50.4%
Limit switch 1 Limit switch 2
Example:
Limit switch 1 (30.4 %) = 3,04 V
Limit switch 2 (50.4 %) = 5,04 V Example:
Limit switch 1 (30.4%) = 8.864 mA
Limit switch 2 (50.4%) = 12.064 mA
[4 mA + (16 mA x 50.4 x 0,01) = 12.064 mA]
4.9.2 Procedure of limit switch storage
0.1. External DIP switch has to stay on
OFFPress rotary button briefly *
Limit switch 1 flashes on the display
1. Press rotary button briefly * Limit switch 1 flashes on the display
2. Change limit switch 1 Turn rotary button
3a. Press rotary button briefly Limit switch 2 flashes on the display
3b. Press rotary button more than 3 seconds “SAVE” is indicated on the lower display during
2 seconds
4. Change limit switch 2 Turn rotary button
5a. Press rotary button briefly Limit switches are not stored
5b. Press rotary button more than 3 seconds “SAVE” is indicated on the lower display during
