7.4.2.2 S3 / S4
These two switches set the range of the speed feedback voltage. Adjustment within the
range is through the MAX Speed preset.

7.4.2.3 S5 / S6 / S7
These three switches control the function of the relay on terminals 10 - 12.
S5
S6
S7
Energised relay state
OFF
OFF
OFF
Motor NOT stalled
ON
ON
OFF
Motor speed > ±1%
OFF
OFF
OFF
Motor speed > +5% (forward)
As an example, with S6 ON and S5 and S7 OFF, when the motor speed is greater than
±1%, the relay is energised, terminals 11 and 12 are shorted, and terminals 10 and 12
are open. When the speed is less than ±1%, the relay is de-energised and the opposite is
true: terminals 10 and 12 are short and terminals 11 and 12 are open.
If more than one of S5 – S7 is ON then the relay operation is the ANDing of the switch
states. For example, if switches S5 and S6 are ON, the relay is only de-energised if the
motor is stalled AND the speed is less than ±1%. In effect, this indicates a failure for the
motor to start.
7.4.2.4 S8
When S8 is ON, speed feedback is taken from the armature voltage. There must be no
connection to terminal T9.
When S8 is OFF, speed feedback is from the TACH terminal T9.

7.4.3.1 Supply Voltage Selector
A link is provided to configure the unit for either HIGH or LOW voltage operation. The
actual operating voltage then depends on the drive model:
