Alarm
Level
: relay driver threshold. +/-(0.5% to 105%). (+/-10.5V).
Symmetrical about zero.
Increasing brightness indicates imminent trip.
Ramp up
: rotate clockwise for a faster response. 20 to 1 seconds up ramp
rate. For +100% speed change.
Minimum speed
: rotate clockwise to increase minimum speed.
*
5K potentiometer provides 0 to 30% of maximum speed.
“Fan failure” alarm is active when lit.
Refer to text.
Maximum speed
: rotate clockwise to increase speed, 40 V to 200 V
(armature or tach feedback V
olts).
LV60 model has
Avf range 10 V to 50 V

Power is present when lit.
The LED is brighter for positive current.
IR compensation
: rotate clockwise to increase level of armature voltage
droop compensation. 0 to 25%. Excessive rotation may cause instability
.
Always set fully anti-clockwise in
Tacho mode.
Level
Ramp down
: rotate clockwise for a faster response. 20 to 1 seconds
down ramp rate. For -100% speed change.
Maximum current
: rotate clockwise to increase current limit.

CAUTION!
EQUIPMENT DAMAGE HAZARD
Do not disconnect the supply while the drive is running. For drives supplied via an
AC supply contactor, either open the T9 RUN input, or ensure that motor shaft is
stationary and is not under load, before opening the contactor.
When using a mains supply contactor, we always recommend to connect a
Normally Open auxiliary contact of the contactor in series with T9 RUN input.

Alternative wiring option
The wiring diagram below shows the addition of speed and
current indicators on Terminal 18 and Terminal 19 respectively.
