Short circuit signals from the OUT connector can be used besides the RS-232
control to control other instruments. The output is active or inactive under the same
conditions as described for the manual control. If the additional inputs HOME, INJ.,
and/or LOAD are in use, the RS-232 connections have priority.
Remote control via Events
Generally the connections on the remote control strip are layed out as open
collector (OC). Therefore the right polarity of any connection has to be obeyed.
2 position valves
Using this valve, the HOME input is inactive. If the LOAD input is short circuited to
the GROUND, only the INJ. and GROUND have to be connected to the signal
sending instrument (i.e. the interface box). If no signal is sent to the INJ., the valve
will be in the LOAD position due to the LOAD GROUND short circuit. If INJ. is short
circuited as well, the valve will switch to the INJECT position. INJ. has a higher
priority than the LOAD.
6, 12, and 16 position valves
The 360° valves only can be operated either in an analog or in a binary mode. For
the corresponding DIP positions refer to table 4 on page 10.
Controlling in analog mode
Short circuit signals from the OUT connector can be used to control other
instruments. The output is only active if the valve is in the HOME position (1). It is
inactive with the valve in positions 2 to 6, 2 to 12, and 2 to 16.
Three input connectors are available. A short circuit signal to HOME moves the
valve to position 1. Similar signals to BACKW./INJ. and FORW./LOAD will move
the valve back or forward one position. To switch the valve twice in the same
direction the short circuit has to be shortly interrupted like a pulse circuit.
The most frequently used connector for the remote control strip is the Knauer
interface box IF2. This wiring is illustrated in Fig. 6. If the drive control takes place
via a pump, refer to the corresponding pump manual for the wiring.
