When the contact is OPEN, the analyzer is analyzing, the
Remote Cal Inputs are being polled, and a zero or span command can
be sent.
When the contact is CLOSED, the analyzer is already
calibrating. It will ignore your request to calibrate, and it will not
remember that request.
Once a zero or span command is sent, and acknowledged
(contact closes), release it. If the command is continued until after the
zero or span is complete, the calibration will repeat and the Cal Relay
Contact (CRC) will close again.
For example:
1. Test the CRC. When the CRC is open, Send a zero
command until the CRC closes (The CRC will quickly
close.)
2. When the CRC closes, remove the zero command.
3. When CRC opens again, send a span command until the
CRC closes. (The CRC will quickly close.)
4. When the CRC closes, remove the span command.
5. When CRC opens again, zero and span are done, and the
sample is being analyzed.
NOTE: The Remote Valve connections (described below) provides signals
to ensure that the zero and span gas valves will be controlled
synchronously.
Range ID Relays: Three dedicated Range ID relay contacts. The
first three ranges are assigned to relays in ascending order—Low
range is assigned to Range 1 ID, Medium range is assigned to
Range 2 ID, and High range is assigned to Range 3 ID. Table 3 -4
lists the pin connections.
