11.6 ZERO POINT SETTING
Use the + and – keys at the same time until
the 00 is shown, release the keys to end zero
setting.

11.7 PRESET VALUES

OUTPUT 1:
Switching output for vacuum regulation
H1 : -0.75
Output 1 = 1 when the switching point H1 is
reached. In case of vacuum loss below the
switching point L1, output 1 = 0

OUTPUT 2:
Switching output for «Gripped product» (to PLC)
H2 : -0.65 L2 : -0.55
Output 2 = 1 when the switching point H2 is
reached. In case of vacuum loss below the
switching point L2, output 1 = 0
Turn power off and check the cause
of overload current or lower the cur-
rent load under 125 mA, then restart
Change input pressure to ambient
pressure and perform zero reset again
(see §11.6 Zero Point setting).
Adjust the pressure within applied
pressure range.
Turn power off, and then restart.
If error condition remains, please
return to factory inspection.
