Signal output 2 is for triggering a follow-up machine device. The sig-
nal output is only active in conjunction with an incremental encoder
for the web speed. It is set depending on the web speed and dis-
tance between the metal detector and the follow-up machine device
(parameters 10, 11 and 17). It is automatically reset according to a
variable value (parameter 18).
Only one message may be processed at a time.
➜
Start setup mode.
➜
Select parameter 10 and enter the circumference of the metering
wheel in millimeters (max. 1999 mm).
➜
Select parameter 11 and enter the number of pulses emitted by
the incremental encorder per revolution (max. 500).
➜
Select parameter 16 and set the signal output operating mode
0 = 24 V ON, with signal
1 = 24 V OFF, with signal (works set)
➜
Select parameter 17 and enter the distance (max. 1990 cm) be-
tween the metal detector and the machine device (e.g. lifting point
of a calender roller).
➜
Select parameter 18 and enter the distance for how long signal
output 2 should remain set (max. 199 cm).
➜
Terminate setup mode.
Check the function of the incremental encoder while the web is
moving.
➜
Start setup mode.
➜
Select parameter 19 and compare the displayed and actual web
speeds.
➜
Select parameter 43 and check the input signal of the incremental
encoder at low speed.
0 = 0 V
1 = +24 V
➜
Terminate setup mode.
Commissioning is thus complete
