Analog Signal Outputs
This function switches the analog out-
puts from zero reference to life zero
mode. The optically isolated analog
outputs are available on the terminal
block in the Increased Safety Junction
Box.
Entry of 0: Output signal of 0-10 V (op-
tion 01- V) / 0-20 mA
Entry of 1: Output signal of 2-10 V (op-
tion 0.2-1 V) / 4-20 mA
Use the INPUT-CONTROL pads to
change the value and then activate
ENTER.
NOTE:
The zero and range values may be
programmed. See Sections 3-3l
(page 3-10) and 3-3m (page 3-10).
For the type of voltage output, refer
to the order confirmation or the iden-
tification plate.
See Section 2-2g (page 2-7) for termi-
nal assignments of the analog outputs
in the Increased Safety Junction Box.
i. Flushing
Period
The Flushing Period establishes the
dwell time for calibration gas flow
during a calibration before the calibra-
tion reading is taken. The period may
be selected in the range of 0-99 sec-
onds depending on the calibration con-
ditions. The calibration gas flow should
be identical with the sample gas flow.
Use the INPUT-CONTROL pads to
change the value and then activate
ENTER.
j. User
Code
This is the password protection code
used to prevent parameter changes by
unauthorized persons. The value is fac-
tory set to “1” but may then be changed
to another value. Be sure to record the
user code in a safe place.
Use the INPUT-CONTROL pads to
change the value and then activate
