•
Actuates when DC power supplied to circuits is
unacceptable in one or more parameters. Permanently
configured as failsafe and latching. Cannot be defeated.
Actuates if self test fails.

(Reset by pressing button to remove power. Then
press again and any other button EXCEPT

Digital Remote Cal Inputs:
Accept 0 V (off) or 24
VDC (on) inputs for
remote control of calibration. (See
Remote Calibration Protocol
below.)
See Table 3-3 for pin connections.
Zero: Floating input. 5 to 24 V input across the + and – pins puts the
analyzer into the
Zero
mode. Either side may be grounded at
the source of the signal. 0 to 1 volt across the terminals allows
Zero
mode to terminate when done. A synchronous signal must
open and close the external zero valve appropriately. See
Remote Probe Connector
. (The –C option internal valves
operate automatically.)
