Refit the cover and tighten the four securing screws.
Operating Information
The equipment must not be switched on until after its cover has been fitted and the cover screws have been
tightened to the correct torque. (see fig 2.) When using the external analogue control the jumpers (Fig 2) must
be correctly set and the analogue signal type selected (PO23) before enabling the analogue input with P006.
If this is not done, the motor may start without warning.
The inverter does not have a mains power switch and is therefore live when the mains supply is connected.
When supplied, the inverter has a frequency setpoint range of between 5Hz and 50Hz.
Basic Operation
1. Using the internal potentiometer
(a)
The Trio is pre-set for forward rotation. For reverse rotation move the link from DIN1 (pin 5) and P10+ (pin 1) to DIN2 (pin
6) and P10+ (pin 1) on the control cable connector (see Figs. 2 and 3).
(b)
Apply mains power. The green and yellow LEDs will illuminate to show that power is applied. Turn potentiometer R314
(accessed by removing the right hand gland hole cover (see Fig. 2) fully counter-clockwise, otherwise the Trio cannot be
started.
(c)
Turn the potentiometer clockwise until the yellow LED extinguishes. This indicates that power is now applied to the motor.
Continue turning clockwise to increase the speed of the motor.
(d)
Turn the potentiometer counter-clockwise to reduce the speed of the motor. Turning the potentiometer fully counter-
clockwise will slow the motor to a complete stop and both LEDs will be illuminated (STANDBY mode).
