REMOTE CONTROL SETUP
1.
Place the power switch in the off position.
2.
Connect the cable from the external remote control to the mating receptacle on the rear panel.
3.
Select operation from front panel potentiometer, external 4-20mA current source, or external
0-10 V voltage source as follows:
a.
Press and hold the INT/EXT control for approximately 5 seconds until the present
setting of the speed source is displayed.
b.
Continuing to hold the INT/EXT control will cause the display to cycle through the three choices:
“4.20” indicating the 4-20 mA input, “0.10" indicating the 0-10 V input, or “Pot” indicating that the
Speed Input Potentiometer will be used. When the key is released, the programmed choice will
remain on the display for approximately 3 seconds as confirmation of the speed source choice
made before returning to normal operation.
4.
To adjust the voltage or current scaling for other than zero to full scale:
a.
Press and hold the INT/EXT control (approximately 5 seconds) until the external speed
source is displayed. (“4.20”, “0.10”, or “Pot”)
b.
Release the INT/EXT control and press the DIR control before the external speed
source disappears from the display.
c.
The display will show “Lo” for about 3 seconds and then flash the current speed setting for the low set
point (4 mA or 0 V). To change this setting, adjust the Speed Control Potentiometer to the percent of full
speed desired. To make no change, press the DIR control a second time.
d.
After pressing the DIR control the second time, the display will show “Hi” and then flash
the high (20 mA or 10 V) speed set point. This can be changed by adjusting the Speed
Control Potentiometer, or left as is by pressing the DIR control again.
e.
The third press of the DIR control returns the drive to normal operation.
NOTE:
The 4-20 mA input, the 0-10 V input, and the 4-20 mA output are not scaled separately.
INTernal / EXTernal Operation
1.
The EXTernal mode of operation enables the PUMP READY output, the EXTERNAL START/STOP, EXTERNAL
CW/CCW, 4-20 mA, and 0-10 V inputs, while disabling the INTERNAL START/STOP input (e.g. footswitch) and
front-panel DIR and START controls. The pump speed is determined by the programmed choice of 4-20 mA,
0-10 V, or front panel potentiometer inputs. The front panel STOP/START control overrides the EXTERNAL
START/STOP input to stop the drive.
2.
In the INTernal mode of operation, either the INTERNAL START/STOP input (e.g. footswitch) or the front panel
STOP/START control can start or stop the drive at the speed set by the front-panel SPEED POT.
