CSMPA (Analog : Electronic Motor Protection Relays)
1. Check the rated voltage and apply the control supply to A1 and A2
terminal.
CAUTION : Do not apply 220 V to 110 V model.
2. Check the “TEST/RESET” button operation.
Check the operation of the output contact.
Check if the control voltage and wiring method is correct (Refer to the
contact configuration).
When you press the “TEST/RESET” button, the “O.L” LED is turned ON
(Red) and the relay is tripped.
When you press the “TEST/RESET” button under the relay is tripped, the
“O.L” LED is turned OFF and the relay is reset.
Auto reset function : When it is tripped by the over current, it is reset after 1
Min. (Optional).
CAUTION : For safety, when the motor is operating the “Test/Reset”
button do not work.
3. Set the operating time
The operating time is set on the base of 600% of the rated current in the
characteristic curve.
Set the operating time by considering the operating time and start current
according to the types of the load.
(Ex.: If the start current is 600% of the normal operating current and the
starting is 10sec., set the time knob around 11~12sec. with 10~20%
margin)
Operating time range is 0~30sec.
If the time knob is set to 10sec, the relay is tripped when the start current
(600% of the rated current) is applied for 10sec.
CAUTION : The relay with inverse time characteristics can be tripped to
protect the motor when the motor is started a few times continuously.
When a motor is frequently changing the rotating direction (forward and
reverse), set the operating time longer. For the crane and hoist use, select
the relay with definite time characteristics.
4. Set the operating current
Set the current by considering the rated current of a motor to protect from the
over current.
Check if the rated current of a motor is within the current setting range of
relay.
Set the ‘RC(A)’ (Rated current) knob to the maximum value and then start a
motor.
Under normal motor operation, rotate the ‘RC’ knob to the
counterclockwise until the ‘O.L’ LED turned ON&OFF. The current at this
point in the 100% current rating under real load.
At this point, rotate the ‘RC’ knob to the clockwise until the ‘O.L’ LED
turned OFF. In general case the setting value is around 110-120% of the
rated current. (Ex.: When the ‘O.L’ LED flickering at 20A, the setting
current will be 22A (=20x1.1)
Note : The brackets for connection is offered standard.

1. Tunnel type mounting
Check if the relay operate in overcurrent
Check the “TEST/RESET” button operation
Check if the wiring is correct (Refer to the wiring diagram).
Set the ‘D-time’ and ‘O-time’ knob to the min. ratings.
When the “TEST” button is pressed under tripped condition, the ‘O.L’
LED is turned off.
When you press the “TEST” button again then the lamp turned off and the
relay reset.
In operation, even though you press the “TEST/RESET” button, the
relay do not trip.
2. Set the operating time (Definite time characteristics)
D-TIME (Delay time) : 0.2~30sec.
The motor starting current, which flows when the motor is starting, is
generally 600~800% of the rated current and the delay time varies
according to the load condition. It is the time during which the relay do not
operate by over-current during the starting time.
Set the delay time by use of the ‘D-TIME’ knob.
In case you do not know the delay time, start the motor by setting the ‘D-
time’ knob to the max. position and after checking the time during which
the starting current become stable, set the ‘D-TIME’ (In general pump, the
setting time is 3-5 seconds)
Note : The time delay is forced time delay type, therefore if you make a
mistake to select the time, the motor may burn.
The operating time is the time during which the relay tripped by the over-
current. The relay is tripped after the selected operating time.
Set the operation time by the ‘O-TIME’ knob.
In special case such as for mechanical shock relay, if you set the ‘O-TIME’
to the min value, the relay is tripped at once.
Generally set it to 4~6 seconds.
3. Set the operating current (Similar to that of the screw type)
Set the operation current to protect from over current. Set the current by
considering the rated current
Start the motor by setting the ‘RC (A)’ knob to the maximum position.
Under operating condition, rotate the ‘RC(A)’ knob to the
counterclockwise until the ‘O.L’ LED turned on & off. The current at this
point is the value (100%) under real load condition.
Rotate the ‘RC(A)’ knob to the clock-wise until the ‘O.L’ LED turned off. In
general case the setting is 110~120% of the rated current.
4. Check the LED condition during the operation
Over current
The relay is not tripped during the ‘D-TIME’ under over-current but the
O.L LED turned on and off to indicate that the over-current flows.
If the relay is tripped after ‘D-TIME’ the ‘O.L’ LED turned on.
Phase failure
If a motor does not rotate under phase failure, the high current may flow.
At this time a motor is protected by the over-current protection function.
