Position Display
As shown in figure 2.5a, the position display shows the current position when a transducer
is properly attached to the channel. The first digit is the transducer channel. If you have a
multi-channel module, press the >NEXT@ key to cycle through the additional position displays.
If there is a transducer fault on the input channel, the position display will change to the one
shown in figure 2.5b. The red FAULT LED is lit when there is a transducer fault. If this LED
is on while the position is displayed, the fault is on one of the other channels. Use the >NEXT@
key to switch to the faulted channel. The fault can be cleared by pressing the >CLEAR@ key if
the 'Err1' message is blinking.
Refer to the Error Messages section on page 2-9 for more information on the causes of a
transducer fault.

CURRENT POSITION
Figure 2.5 Position and Transducer Fault Displays
The tachometer display shows the current speed of the
transducer in revolutions per minute with either 1.0 or 0.1 RPM
resolution.
If there is a transducer fault, the display will show the 'Err1'
message instead of the current speed. (See Position Display
above.) The red FAULT LED is lit when there is a transducer
fault. If this LED is on while the tachometer is displayed, the
fault is on one of the other channels. Use the >NEXT@ key to
switch to the faulted channel. The fault can be cleared by
pressing the >CLEAR@ key if the 'Err1' message is blinking.
