AC Semiconductor Motor Controller Instructions
Ramp up potentiometer: the motor starting
time in a direct-on-line start depends on the
characteristics of the motor load; the ramp up
time must be longer than this time period so
that the bypass relays are activated after the
starting current has dropped to a steady level.
Ramp down potentiometer: the motor stop-
ping time may be extended by gradually
reducing the voltage over the ramp down time.
The actual time taken to start and stop the
motor will vary according to the combinations
of above settings and the type of motor load
itself.
Initial Torque potentiometer: this adjusts the
starting voltage and must be set to enable the
motor to start rapidly. The soft start is a result
of both initial torque and ramp up time adjust-
ments.
Suitable for use on a circuit capable of deliver-
ing not more than 5000 rms symmetrical
amperes, 600V maximum when protected by
R/C fuses Cat No. 6.621 CP URQ 27x60/
"Amp rating" , rated maximum 280% of con-
troller full load amperes and 600Volts.
Suitable for use on a circuit capable of deliver-
ing not more than 5000 rms symettrical
amperes, 600V maximum when protected by
RK5 fuses, rated maximum 225% of controller
full load amperes and 600Volts.
MODE OF OPERATION
IMPORTANT
Should you require information about installa-
tion, operation or maintenance of the product
that is not covered in this instruction docu-
ment you should refer the matter to an autho-
rised Fanox representative. The information in
this document is not considered binding on
any product warranty.
ATTENTION
1.To prevent electrical shock, disconnect from
power source before installing or servicing.
2.The bypass relays in the main circuit may be in an
undefined switching state due to hand-ling during
shipping. It is recommended to make the first cycle
with the motor disconnected, to set the bypass
relays to a defined switching state. If not performed,
this may cause unexpected operation of the motor.
3.The ES has been designed as Class A equipment.
Use of the product in domestic environments can
cause radio interference.
4.It is important to utilise this product according to
its specified overvoltage category.
5. At high ambient temperatures, it is important to
allow sufficient cooling time between starts.
6. The maximum ambient temperature is 50°C when
devices are mounted side by side. For stand alone
devices or with proper spacing between the devices,
the maximum ambient temperature is 60°C.

Status Indication LED
Check power cable connections to L1, L2, L3.
(Internal power supply is connected to L1, L2.)
Check also fuses, contactors and motor pro-
tection devices. Line voltage is too low-meas-
ure line voltage.
Check cable connections from T1, T2, T3 to
motor terminals. Check control input connec-
tions to A1, A2. There is a delay of 0.5s
(approx.) until ramping starts, after applying
control voltage.
Device has over-heated. Allow time to cool
down. Check that number of starts per hour
does not exceed specified level.
PTC alarm has occurred. If motor PTC is not
connected, ensure that PTC terminals P1, P2
are connected to each other with a loop. If
motor PTC is connected, motor may have
over-heated. If motor has not over-heated,
PTC sensor may be faulty.
Missing phase voltage. Check power cable
connections to L3. If either L1 or L2 is missing,
[POWER ON] and [Ø LOSS] LEDs will be OFF.
Incorrect phase sequence. Change the termi-
nal position of two of the power supply
cables connected to L1, L2, L3.
[POWER ON] is OFF
Alarm
activated
After noting type of alarm, disconnect mains
supply L1, L2, L3. Re-connect only if problem
has been resolved. This resets device.
Any alarm LED is ON
[POWER ON] is ON
[OVERHEAT] is
ON intermittently
[OVERHEAT] is
ON continuously
[Ø LOSS] is ON
[WRONG Ø] is ON
