undercurrent or instantaneous overcurrent trip levels. The

flags can signal the situation to external equipment via one

of the programmable outputs. The flags clear when the

current returns within the normal operating range by 10% of

the programmed motor full load current.

4-10 Low Current Flag

Range: Function:

50%* [1% - 100% FLC] Sets the level at which the low current

flag operates, as a percentage of motor

full load current.

4-11 High Current Flag

Range: Function:

100%* [50% - 600%

FLC]

Sets the level at which the high current

flag operates, as a percentage of motor

full load current.

7.7.4 Motor Temperature Flag

The MCD 500 has a motor temperature flag to give early

warning of abnormal operation. The flag can indicate that

the motor is operating above its normal operating

temperature, but lower than the overload limit. The flag can

signal the situation to external equipment via one fo the

programmable outputs.

4-12 Motor Temperature Flag

Range: Function:

80%* [0% - 160%] Sets the level at which the motor

temperature flag operates, as a percentage

of the motor's thermal capacity.

7.7.5 Analog Output A

The MCD 500 has an analog output, which can be connected

to associated equipment to monitor motor performance.

4-13 Analog Output A

Option: Function:

Selects which information will be reported via

analog output A.

Current (%

FLC)

Current as a percentage of motor full load current.

Motor

Temp (%)

Motor temperature as a percentage of the motor

service factor (calculated by the soft starter's

thermal model).

Motor kW

(%)

Motor kilowatts. 100% is motor FLC (Par. 1-1)

multiplied by mains reference voltage (Par. 8-9).

Power factor is assumed to be 1.0.

4-15 Analog A Maximum Adjustment

Range: Function:

100%* [0% - 600%] Calibrates the upper limit of the analog

output to match the signal measured on an

external current measuring device.

4-16 Analog A Minimum Adjustment

Range: Function:

0%* [0% - 600%] Calibrates the lower limit of the analog output

to match the signal measured on an external

current measuring device.

7.8 Start/Stop Timers

CAUTION

The auto-start timer overrides any other form of control. The

motor may start without warning.

5-1 Auto-Start Type

Option: Function:

Selects whether the soft starter will auto-start after a

specified delay, or at a time of day.

Off

The soft starter will not auto-start.

Timer The soft starter will auto-start after a delay from the next

stop, as specified in Par. 5-2.

Clock The soft starter will auto-start at the time programmed in

Par. 5-2.

5-2 Auto-Start Time

Range: Function:

1 min* [00:01 - 24:00

(hrs:min)]

Sets the time for the soft starter to

auto-start, in 24 hour clock format.

5-3 Auto-Stop Type

Option: Function:

Selects whether the soft starter will auto-stop after a

specified delay, or at a time of day.

Off

The soft starter will not auto-stop.

Time The soft starter will auto-stop after a delay from the next

start, as specified in Par. 5-4.

Clock The soft starter will auto-stop at the time programmed in

Par. 5-4.
