Remote Start (40016)
Momentarily place a 1 in this register to remotely place the system in Auto. To place a
momentary 1 in this register, you need to write a 1 to this register for at least 1 second,
followed by writing this register back to zero.
Remote Stop/Permissive Run (40017)
Momentarily place a 1 in this register to remotely place the system in Manual. Maintaining
a 1 in this register functions as a remote lockout. To place a momentary 1 in this register,
you need to write a 1 to this register for at least 1 second, followed by writing this register
back to zero.
Remote Blowdown/Sample Control (40019)
0 = Local control of system
1 = Remote blowdown
2 = Remote Sample
Use this register to control the mode of the Sample Sentry II. A 0 in this register gives local
control to the system. Blowdown and Sample modes are initiated based on controller
setup parameters. Placing a 1 in this register places the system in Remote Blowdown. SV-2
remains closed preventing flow to online analyzers. The system overrides the blowdown
timer, remaining in the blowdown condition until this register changes or the system is
shutdown. Placing a 2 in this register places the system in Remote Sample.
