The following procedure 1-7 is only necessary if
no belt revolution sensor is
detected / installed
. (Procedure will then be the same as for model A2-H14.)
The steps below must then be carried out under
“Run Belt”.
1.
Make a clearly visible mark on the belt, or use a belt joint as a reference mark.
2.
Set the switch inside the connection box(-G) to the
TEST
position.
(
tacho pulses stopped
). If there is no switch, connect a jumper wire between
terminal 5 and 6 and arrange it so that it can be quickly and easily disconnected when
counting is terminated.
3.
Activate counting by selecting “Yes”. “
Pulses
0
” will be indicated in the display
window.
4
. Start the conveyor.
5.
When the reference mark passes a pre-determined point, Set the switch to
the“
RUN
” position. After one revolution of the belt, i.e. when the reference point
passes the fixed point, return the switch to “
TEST
”.
6.
Press the frontkey “
B
” (the number of pulses will now be saved).
7.
Set the connection box switch back to the “
RUN
” position, otherwise the
tachometer will not work. If it is possible to see the mark on the belt from where the
controller is located, the tachometer pulses may be stopped or started using the
frontkey “
B
” only. (this eliminates the use of the switch inside the conn.box -G).
If a tachometer type “SEG CF” is being used, i.e. driven by the return part of the belt,
the corresponding belt length is now automatically displayed under “
BeltLen=
”.
If you are driving the tacho by other means, or using a contactor input, then you must
accurately measure the belt length and enter the value under “
BeltLen=
”.
NOTE 1
If a previous start-up already has been carried out, new limit values for zero
setting of belt will not be calculated. If new values are desired, the parameter values
for “
CutOff”
and “
AutNMax
” must be zeroset before
“Run belt
” is performed.
New values will also be calculated when desired if zeroset before initiating a “system
zero” from inside the menusystem.
NOTE 2
If “
PulsLen”
and “
BeltLen
” is already known, for example from a previous
start-up, counting pulses for 1 belt revolution is not necessary.
Just select “
Yes
” (Belt must be stopped at this time) and push enter to confirm.
If start-up is done without belt position sensor and later detected during “SysZero”, it will be used and belt length
readjusted automatically.
