Description
rsel [channel parameter release_ppm
set_ppm release_value set_value
startup_value error_value]<cr>
Configure relay operation of the channel.
channel
= Analog output channel
• 1 = voltage output (V): not used with relay
•
2
= current output (mA): only use this option with
the relay box.
parameter
= The parameter that is output on analog
channel. The only option is
CO2
(in ppm).
release_ppm
= CO
2
level at which the relay is
released.
set_ppm
= CO
2
level at which the relay is activated.
release_value
= The current output (mA) when
the relay is released.
set_value
= Current (mA) output when the relay is
activated. Set to
12
when using the relay box with
GMP251/252.
startup_value
= During probe start-up, if the CO
2
ppm level falls between the
release_ppm
and
set_ppm
values,
startup_value
shows the state
of the relay (mA): the relay is either activated,
released, or in error state.
error_value
= The current (mA) that is output
when the probe is in an error state.
