7.5 J8 – Analog (Signal) Input Voltage –
The output of this control is normally controlled
with the main potentiometer. However, an
analog voltage (isolated) may also be used in
place of a potentiometer. The control can be
scaled for 0 – 10VDC by placing J8 in the
appropriate position "15V" or "10V". The scaling
can be further adjusted with the SCALE Trimpot.
Refer to Section 6.9, (Signal Following) on page
17, and Figure 16, for additional information.
7.6 J17 – Analog Signal Input – J17 is used in
conjunction with jumper J8 and the Main
Speed Potentiometer for, the input of a voltage
or a voltage or current signal
. Refer to Section
6.9, (Signal Following) on page 17 and Figures
17A and 17B.
7.7 J9 – Enable (EN) / Inhibit (INH) – The control
can be electronically stopped or started with the
inhibit circuit, depending upon the position of
Jumper, J9. The control can also be started and
stopped with the Enable (Factory Set) function.
(The enable circuit functions opposite to that of
the inhibit circuit). See Figure 18 and Section
6.10, on page 18, for wiring information.
