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 Volts).
LV60 model has Avf range 10 V to 50 V.

Power
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.
0 to 100% current limit.
Stability: gain 1 to 10.
