For voltage modes, a stable, variable DC voltage source can be used in conjunction with a DC
voltmeter, (max 30V DC). (Refer to the 25 pin terminal strip wiring detail as an example of
control circuitry). Circuit impedance 100k
Ω
. Polarity set for non-inverted response. Reverse
polarity for inverted response.
For current modes the same DC source can be used in conjunction with a DC milliampere
meter, (maximum 32mA). (See 25 pin terminal strip detail). Circuit impedance 250
Ω
. Polarity
set for non-inverted response. Reverse polarity for inverted response.
Pump -
When under RS232 control each individual pump must be identified. Select a number from 1-16.
Baud -
Speed of signal transmission. Default setting 9600, range of setting include 1200, 2400, 4800, 9600.
Trim -
This function will match the pumps signal conditioner to the analogue process control signal if they do not fully coincide. The user will
be asked to apply zero, 20% and the maximum voltage or current that is required to be the control signal. Press enter after adjusting the
process signal to each input level.
Never apply mains voltage across pins on the 25 pin terminal strip. Up to 5V TTL may be applied to pins 7 and 5,
but do not apply voltage across any other pins. Failure to comply could cause permanent damage not covered by
warranty. Do not use the mains power switch to control the pump for a high repetition of stop.starts. The
auto-control facility should be used.
Autostart -
If set to
On
when in
Manual
mode only, Autostart will allow the pump to restart pumping automatically after power-up following a
mains supply interruption. If set to off the pump will restart and return to the Main Menu.
Remote Stop -
Provides the option for keypad over-ride of remote stop.
Strobe -
Monitor the pump dosing or motor state/direction of rotation using 2 high (5V) /low (0V) auxiliary signals outputted via the pumps 25
pin terminal strip. Auxiliary signals can be used, for example, to command a turntable or conveyor to move when a dose has been completed.
Line 1
can be set to change state every time the motor runs, or only when the motor runs to dispense a dose. The signal can be set high or low
when the motor runs.
Line 2
changes state when the pump direction is changed. The screens allow the signal to be set high or low when the
output shaft rotates clockwise.
Default -
Press
Enter
at “
Yes
“ to
restore factory defaults.
Remote control
Never apply mains voltage across pins on the 25 pin terminal strip. Up to 5V TTL may be applied to pins 7 and 5,
but do not apply voltage across any other pins. Failure to comply could cause permanent damage not covered by
warranty. Do not use the mains power switch to control the pump for a high repetition of stop.starts. The
auto-control facility should be used.
Pause dose
This function will pause a dose on for as long as a remote switch remains closed then allows the dose to continue when the switch is opened.
Under Manual mode it will also act as a remote stop/start. Connect remote switch as in the Stop/Start diagram. Open to run pump, close to
pause or stop pump.
