Configuration: Device test: Inputs/outputs: Test of relays
You can use this function to test the status of the relays con-
trolled by this analyzer.
First enter the relay to be tested in this dialog. The analyzer can
control up to eight relays, or up to 16 relays with an add-on
board, whose contacts you can test. Connect an ohmmeter to
the corresponding relay outputs on the plug.
You can process the following parameters:
• Relay number:
One of the relays 1 to 8 (relays 1 to 16 in the case of
analyzers with add-on board)
•
Condition:
The current state of the selected relay (active or inactive;
inactive in the Fig.).
The pin assignments of plug X80 (motherboard) und X50 (add-
on board) are described in section Pin assignments (Page 54).
You can exit the test by pressing the <ESC> key.
Configuration: Device test: Inputs/outputs: Test external solenoid valve
You can use this function to trigger external solenoid valves for
the zero and calibration gas supplies via the relay contacts.
Use the arrow keys <
↑ > and < ↓ > to select the zero gas valve
(ZV) in the first line or the calibration (span) gas valve (SV) in
the third line, and call the selected valve using the <ENTER>
key.
Switch the previously assigned relay using any arrow key in the
second or fourth line (the value on the right edge of the line
toggles between OFF and ON). The currently measured values
are output in the menu displayed during the test.
