7.5.8 Adjusting long-stroke capacity rod for SAB 283 Mk1
For type part no. 1373-038
Note: For long-stroke transmitters with part no. 1373-057 calibration and terminal connec-
tion are similar to that of SAB 110, SAB 128 etc. Please see subsection 7.5.7.
As shown in Fig. 32, the capacity transmitter is fitted with a single calibration button surroun-
ded by a green and red LED.
During normal operation the red LED flashes rather slowly. The green LED is switched on con-
stantly when the transmitter is in 100% position whereas it flashes quickly when the transmit-
ter is in 0% position.

Calibration is carried out as follows:
1. Apply supply voltage minimum five minutes before calibration.
2. Move the slide to minimum position and press the calibration button once. The red
LED will switch ON. After a while, the red LED will turn OFF indicating that it is ready
for 100% calibration.
3. Move the slide to its maximum position and press the calibration button again. The
red LED will start flashing quickly. After a while the red LED will flash normally and
calibration is completed.
