9.2.1 FOR 4 WIRE SOLUTIONS (H & LY SERIES)

• Measure the ‘Neutral’ to output voltage and adjust each line as required.

Example, place the first meter probe on the output ‘Neutral’ and the other meter

probe on the output ‘L1 Phase’ - adjust pot ‘VR1’, until the voltage meets the

required value.

• Continue with the other two output phases - L2 & L3 - with the first probe still on the

‘Neutral’, the other probe on the relevant output phase and adjustments being made

to relevant phase pot on the Servo Amplifier PCB.

9.2.2 FOR 3 WIRE SOLUTIONS (HD & LD SERIES)

• Measure the ‘output voltage Line to Line ie. L1 to L2 and adjust as required.

Example, place the first meter probe on the output ‘L1 Phase’ and the other meter

probe on the output ‘L2 Phase’ - adjust pot ‘VR1’, until the voltage meets the

required value.

• Continue accordingly with the other two output phases - L2 to L3 and L3 to L1 with

adjustments being made to relevant phase pot on the Servo Amplifier PCB.

9.3 OVER / UNDER VOLTAGE & PHASE FAILURE PROTECTION

• SW1 Switch on the Servo Amplifier PCB activates the Over / Under Voltage & Phase

Failure Protection features.

By default these protection features are deactivated.

• With activation, should the outgoing voltage from the Stabiliser drift, other than

momentarily, by 15% or more, the Stabiliser’s input circuit breaker will automatically

trip – thereby protecting the load.

• To minimise the possibility of nuisance tripping, this setting is set by default at 15%.

If required, the sensitivity setting can be recalibrated to 9% – please refer to the

Ashley-Edison Service Department for guidance. However, in the interest of ease

for all, it is normally recommended that the machine be supplied already pre-

calibrated by our factory engineers for the lower setting.
