
System Alarm:

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 System to
resume.
Further detail can be found in chapter 4, section 4-5.
3.3.5 Digital Remote Cal Inputs
Remote Zero and Span Inputs: The REMOTE SPAN and
REMOTE ZERO inputs are on the DIGITAL INPUT terminal block.
They accept 0 V (off) or 24 VDC (on) inputs for remote control of
calibration. (See
Remote Calibration Protocol below.)
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 section
3.3.9
Remote Sensor and Solenoid Valves . (With the –C option
internal valves operate synchronously.)
Span: Floating input. 5 to 24 V input across the + and – pins puts the
analyzer into the Span mode. Either side may be grounded at the
source of the signal. 0 to 1 volt across the terminals allows Span
mode to terminate when done. A synchronous signal must open
and close external span valve appropriately. See section 3.3.9
Remote Sensor and Solenoid Valves . (With the –C option
internal valves operate synchronously.)
Cal Contact:
This relay contact is closed while analyzer is
spanning and/or zeroing. (See Remote Calibration Protocol below.)
Remote Calibration Protocol: To properly time the Digital
Remote Cal Inputs to the Model 3000TB Analyzer, the customer's
controller must monitor the Cal Relay Contact.
