Configuration: Device test: Inputs/outputs: Test of relays
You can use this function to test the status of the relays co
n-
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. Co
nnect 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 th
is 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 l
ine (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.
