DIP SWITCH
Cleaning function
Cleaning function connected in ON position.
When the rotor has stopped for 10 minutes, the cleaning function is
activated and the rotor starts to rotate. As advance warning, the rotor
rotates with a motor speed of 5 rpm for the first 6 seconds,
following which the rotor stops for 3 seconds. After this, the actual
cleaning function starts, for a random time, between 10 to 20 seconds
with the motor at 20 rpm.
External rotation
monitor
The internal rotation monitor is normally used, in which case the
DIP switch must be in the OFF position.
If the external rotation monitor is used, this is connected at terminal
connections 9 and 10, in which case the DIP switch must be in the ON
position.
High speed *)
The rotor rotates at the set max. rpm when the DIP switch is set to ON.
Low speed *)
The rotor rotates at the pre-set min speed (1 rpm) when the DIP switch is
set to ON.
Modbus termination
If the control unit is last in the Modbus loop, the DIP switch must be in
the ON position.
*) Manual operation (during test)
OPERATIONAL INDICATIONS
On
Lit with fixed light
It flashes when the control unit has tripped.
Run
Comes on when the motor is to rotate, i.e. when the input signal exceeds
the threshold value.
Flashes during the cleaning function sequence.
Rotation
Internal rotation monitor
External rotation
monitor
Flashes after each approved measurement, although only when the
“External rotation monitor” DIP switch is in the OFF position; for more
information, see “Description of functions” on page 4
Flashes when the magnet passes the rotation monitor, regardless of the
setting of the “External rotation monitor” DIP switch.
Flashes even if the input signal is lower than the threshold value.
Modbus
If Modbus must be used, refer to the separate manual on our website,
www.ibccontrol.se.
