OPERATING ENVELOPE
Natural reflective surfaces within the machine may
increase the signal transmission range.
Coolant residue accumulating on the OMP diodes
and OMM or OMI window, will have a detrimental
effect on transmission performance. Wipe clean
as often as is necessary to maintain unrestricted
transmission.
Operation in temperatures of 0 °C to 5 °C or 50 °C to
60 °C (32 °F to 41 °F or 122 °F to 140 °F) will result in
some reduction in range.
WARNING
If two systems are operating in close proximity
take care to ensure that signals transmitted from
the OMP on one machine, are not received by the
OMM or OMI on the other machine, and vice
versa.
OMM and OMI POSITION
To assist finding the optimum position of the OMM
during system installation, signal strength outputs
are available on the MI 12 interface.
OMI signal strength is displayed on an OMI
multicoloured LED.
