6-2 Automatic Operation
Trial Operation
Equipped with floats to detect the water level and an internal control circuit, the automatic type (CA) pump
can perform an automatic drainage operation alone by merely connecting its cable to a power supply.
Connect the power and perform a trial operation as follows:
Allow the pump to operate a minimum of 2 seconds for each trial operation. The trial operation must be com-
pleted within 1 minute.
Note:
In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales office in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or fire.
CAUTION
6-3 Automatic Alternating Operation
Trial Operation
The (CW) automatic alternating type pump is used in conjunction with the (CA) automatic type. Equipped
with floats to detect the water level and an internal control circuit, it can perform an automatic alternating
drainage operation by merely connecting its cable to a power supply.
Connect the power and perform a trial operation as follows:
(1) Direct all the floats downward.
(2) First raise the (red) stop float, then the (yellow) start float.
This will cause the pump to start.
(3) Next, return the (yellow) start float, and then the (red) stop
float to their original positions. This will cause the pump to
stop.
(4) Perform steps (2) and (3) consecutively two or more times to
verify the operation.
It takes approximately 1 second for the pump to start after the f oat is moved. Allow the pump to operate a
minimum of 2 seconds for each trial operation. The trial operation must be completed within 1 minute.
Note:
In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales office in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or fire.
CAUTION
(7) Next, return the (green) parallel operation float, then the (yellow) alternating start float, and then the (red)
stop float to their original positions. This will cause the pump to stop.
(8) Perform steps (6) and (7) consecutively two or more times to verify the operation.
(1) Direct all the floats downward.
(2) First raise the (red) stop float, then the (yellow) alternating start float.
(3) Next, return the (yellow) alternating start float, and then the (red)
stop float to their original positions. This will cause the pump to stop.
(4) Perform steps (2) and (3) consecutively three or more times to verify
the operation. The pump will start and stop every other time.
(5) Again, direct all the floats downward.
(6) After performing the trial operation of pump by the step (2) and (3).
Raise the (red) stop float, then the (yellow) alternating start float, and
the (green) parallel operation float. This will cause the pump to start.
