Hi!

This page is actually a small piece of a much larger site called SciLog.com
You most likely got here from a search engine or other link... that's fine when you're done just head over to the main site. Or if you think there is a problem contact us.

I/O Ports:

DB 15 (Back Panel)
RS-232 Serial port, DB15 connector, pin 2 (Transmit), pin 3 (Receive) & pin 5 (Ground)
4-20 mA input signal, DB 15 connector, pin 6 (Ground) & pin 13, with selection switch (back panel) at 4-20 mA
0-5VDC input signal, DB 15 connector, pin 6 (Ground) & pin 13, with selection switch (back panel) at 0-5VDC
Pump Speed output signal, DB 15 connector, pulsed output between pins 7 (Ground) & pin 9, pulse rate is proportional to pump speed, ~5940 pulses/sec at 99% pump speed, ~3000 pulses/sec at 50% pump speed.
Remote Start/Stop ( Remote ), closed contact closure (RUN), open contact closure (STOP) between pin 8 (Ground) & pin 15 of the DB 15 connector. This function is active when REMOTE has been selected from the front panel.
Remote CW/CCW Motor Direction ( Remote ), closed contact closure (CCW), open contact closure (CW) between pin 7 (Ground) & pin 14. This function is active when the REMOTE mode has been selected from the front panel.
Remote Start/Stop ( Local ), closed contact closure (RUN), open contact closure (STOP) between pin 8 (Ground) & pin 15 of the DB 15 connector. This function is active when the LOCAL mode has been selected from the front panel and the external contact closures (CC across pin 8 & 15) has been exercised, i.e. opening and closing the connected contact closures (CC). The front panel RUN/STOP key will be disabled at that point, however, the pump speed selection and the CW/CCW keys are still functional. The front panel RUN/STOP key function can be re-established by twice pressing the LOCAL/REMOTE key. NOTE: This operational mode should only be used when the ACCU pump is to be controlled (Stop/Start) by a SciLog Smart Pump, i.e. UltraTec or ChemTec.
Foot Switch Start/Stop ( Local ), foot switch acts as an external contact closure, pump runs at the selected pump speed as long as the foot switch contact is closed, i.e. as long as you step on the foot switch. The pump stops when the foot switch contact is open.

Data Entry: Membrane keyboard, 2 LED's with auditory feedback.
