Figure 8: Control Panel Switches

LS5 - Load on bypass:

This led illuminates when the output isolator is closed and the load is connected to the bypass via the static switch.

LS6 - Load on Inverter:

This led illuminates when the output isolator is closed and the load is connected to the inverter via the static switch.

Control switches

Seven tactile switches are located on the Operator Panel, together with an emergency stop push button which is fitted with a safety cover to prevent inadvertent operation.

Switch S1 (Vo) - Output volts:

When this switch is pressed, the lower line of the LCD Display shows the output phase voltage w.r.t neutral.

Switch S2 (Fo) - Output frequency:

When this switch is pressed, the lower line of the LCD Display shows the output frequency.

Switch S3 (Io) - Output current:

When this switch is pressed, the lower line of the LCD Display shows the output current.

Switch S4 (B) - Battery:

When this switch is pressed, the lower line of the LCD Display shows the battery voltage and current. Note that a discharging current is symbolised by a preceding minus (-) sign, plus autonomy time is displayed according to % load for SMF batteries.

Switch S5 ((∙)) - Alarm reset:

Pressing this switch cancels the audible alarm. The alarm led and messages will remain active if a detected fault condition is still present.

Switch S6 - Inverter OFF:

Pressing this switch turns OFF the inverter and causes the load to be transferred to the static bypass supply.
