Table 38: Status Page Sections
Section Purpose
Analog Inputs
Shows the current calibrated value being received at each of the IO board’s four analog
inputs. Displayed measurement units are based on the factory calibration of these inputs.
Pressure
is the measurement cell pressure input,
RTD1
is the measurement cell
temperature input, and RTD2 is the probe temperature input (if present).
Calculated
Analog Outputs
Shows the present expected current output, in milliamps, from each of the four analog
outputs on the IO board. These current outputs are based on the analog output’s configured
parameter and range.
Relays (P4
Connector) Test
Shows the current status of the IO board’s four digital (relay) outputs. A grey indicator
indicates the relay is in the deenergized (alarm) condition, while a red indicator indicates
that the relay is in the energized (normal) condition. P4 Connector indicates that the relay
connections are made to the P4 terminal block on the IO board.
Solenoids (P6
Connector) Test
Shows the current status of the IO board’s four solenoid control relays. A grey indicator
indicates the solenoid is deenergized, while a red indicator indicates the solenoid is
energized. P6 Connector indicates that the solenoid connections are made to the P6
terminal block on the IO board.
• Solenoid 1 = cabinet cooler solenoid
•
Solenoid 2 = Sampling / Backpurge solenoid (energized = sample, deenergized
= backpurge)
• Solenoid 3 = probe cooler solenoid
•
Solenoid 4 = oven heater control relay
Digital Input
Shows the current status of the IO board’s single digital input. Red indicates the digital input
is receiving a signal, while grey indicates it is not receiving a signal. This input can be used
for remote triggering of a zero calibration cycle.

Manual Override Page
The Manual Override page shown in Figure 94 allows the user to take control of the IO board
for the purpose of calibrating and testing all available outputs, both analog and digital.
This page allows the user to take control of and make changes to the configuration
of the IO board of the analyzer. Any change made to the analog output calibration
will permanently delete the present value. Access to this page should be limited to
qualified users who understand the consequences of making changes on this page.
