Footswitch
Connect to the external control interface. Control the start and

Note:
Footswitch is optional accessories. It can only control the start
and stop of the pump. The speed and direction of the pump are
controlled by the knob and switch on the operation penal.
Lead-2 can connect to the control computer (computer, PLC, SCM)
through RS485 serial communication interface.
Note:
1.The pump I.D. of the pump which connects to the control
computer through RS485 serial communication interface must
be unique to prevent the communication from error.
2.Please contact Longer Company for communication protocol.
When the pump is idle, we recommend you to release the tubing
from pressure. This helps to protect the tubing from unnecessary
strain and prolongs its service life
Keep rollers clean and dry. This will prolong the service lives of
tubing and pump head.
The surface of drive and the pump head are not organic solvent
and aggressive liquids resistant. Please pay attention when using.
Note
If a trouble happens please contact us or our dealers.
The warranty period for this product is one year. If repair or
adjustment is necessary within the warranty period, the problem
will be corrected at no charge if it is not due to misuse or abuse on
