2. Using the Watson-Marlow external potentiometer (when fitted):
(1)
Apply mains power.
(2)
Start the motor using the I/0 switch and adjust the potentiometer to obtain the desired speed.
(3)
Reverse the direction of rotation using the
switch.
3. Using the OPm2 hand held controller to select a set running speed
(a)
Plug the OPm2 hand held controller into the Trio (see Fig. 1)
(b)
Select the required language using the up key
I
and down key
J
and then press P (this screen only appears the first time
the OPm2 is plugged in).
(c)
To select the required running frequency: Press P and then s to parameter P005, Press P, then
I
or
J
to alter the default
setpoint (default value = 50Hz), Press P to store.
(d)
Press
I
to parameter P006. Change to 0 to specify digital input.
(e)
Press
I
to parameter P007. Change to 1 to enable the OPm2.
(f)
Press the Menu button and then select OPERATE using the P button.
(g)
Press the ON (I) button on the OPm2. The inverter will now run at the frequency set by P005. Adjust the frequency using the
I
and
J
keys.
(h)
Adjust other parameters as required to suit operating conditions (see parameter summary list at rear of manual).
1 Motor current
2 Parameter number
3 Current status
4 Motor direction
5 F=current, S=setpoint frequency
6 Motor rpm
7 Motor voltage
8 Motor torque (% max)
Other OPm2 functions
The parameter settings required can be entered using the three buttons (P
I
and
J
) on the front panel.
The parameter numbers and values are indicated on the LED display.
Pressing the Jog button while the inverter is stopped causes it to start and run at the preset jog frequency factory preset 5Hz. The
inverter stops as soon as the button is released. Pressing this button while the inverter is running has no effect. Disabled if P123
= 0.
•
Press I to start the inverter. Disabled if P121 = 0
•
Press 0 to stop the inverter.
•
Press
to change the direction of rotation of the motor. REVERSE is indicated by a minus sign (values <100) or a
flashing decimal point (values > 100). Disabled if P122 = 0.
•
Press
I
to INCREASE frequency. Used to change parameter numbers or values to higher settings during the
parameterisation procedure. Disabled if P124 = 0.
•
Press
J
to DECREASE frequency. Used to change parameter numbers or values to lower settings during the
parameterisation procedure. Disabled if P124 = 0.
•
P Press the access parameters. Disabled if P051 - P053 = 14 when using digital inputs.
Note:
If the motor does not run after parameters have been changed accidentally, reset the inverter to the factory default
parameter values by setting parameter P944 to 001 and then pressing P.
