By interlinking the contacts no. 4 and 5 of the socket at the rear of the pump (see section 10.2), the pump will be blocked and the ON/OFF LED will be switched off.
The same effect will be obtained by applying a voltage of 3 to 12 V DC to the contact no. 5 (0 line must be connected to contact no. 3).
Note: Please contact us, if a reverse logic is needed for remote control of the LAMBDA laboratory peristaltic pump.
The LAMBDA Peristaltic pumps can be controlled over the whole speed range by an external signal (0 - 10 V DC, option 0-20 or 4-20 mA). The plus pole of the signal is connected to the contact No. 1, 0 line to the contact No. 3.
The indication on the display may become unstable when no external connection is made and indicates the high sensitivity of the electronics.
For safety reasons the voltage of the external signal must not exceed 48 V to earth!
If the instrument has been equipped with the optional RS-232 or RS-485 interface (optional), it can be controlled digitally, e.g. from a PC by PNet peristaltic pump control software.
