Alignment of Senders & Receivers
4.2 OMROM E3Z SAFETY SENSOR ALIGNMENT. CONT.
Ensure that the machine is level and all four leveling jacking bolts are correctly adjusted. Check the
rear guards are bolted tight and adjust the stabilizing feet to ground level to support the guards.
The sensors are sensitive to alignment so try to align as accurately as possible. If the sender is only
just aligned with the receiver, any vibration when cutting will stop the pump and the safety circuit
will have to be reset again.
Loosen the sender screws and angle sender up until receiver loses alignment.
Angle sender down until receiver re-aligns and then loses alignment again.
Half way between these two positions is the most accurate alignment.
The sensors may also have to be angled sideways as well to get the best possible alignment. This may
involve packing individual brackets or sensors.
You can now reset the safety circuit & press OK
on the NC89.
After a successful reset the NC89 screen should
be the same as Fig. 1
Fig. 1
The Pump can now be started
