®
Series Gas Monitor is shipped with the Sensor Swap Delay
enabled. This means that the 4-20 mA output signal and the FAULT relay will
hold off a fault indication for 60 seconds after the missing sensor indication is
displayed on the instrument. This setting allows the operator to exchange sen-
sor modules without a FAULT indication.
