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.
Tachometer Display
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.
