Two Digital Inputs; One Status Relay Output - Inficon Transpector XPR 3+ Operating Manual

1.17.1 Two Digital Inputs

Logic Inputs 1 and 2 are by default set to remotely control emission status.
Connecting Pin 14 (Logic Input 1) to Pin 15 (Ground) will turn on the emission.
Connecting Pin 13 (Logic Input 2) to Pin 15 will turn off the emission. See
Table 1-2 Digital inputs

CAUTION
Controlling emission through the digital inputs bypasses
all software or hardware interlocks. When using digital
inputs for controlling Transpector XPR 3+ emission,
develop an interlock that will not allow the emission to
turn on if the pressure is too high for operation of
Transpector XPR 3+.
