OVERVIEW
The control unit BX308 XP has been designed and built to meet
the current requirements of the Market and in compliance with
European Standard for checking gas presence in a versatile and
innovative using conventional sensors.
Up to 8 remote sensors from 4-20mA can be connected in
conventional mode for a single area. Gas concentration measured
by each sensor is sequentially shown on display, with a location
description.
When one of the connected sensors exceeds pre-alarm or main
alarm setpoints, the control unit activates the internal audible alarm,
depending on the concentration of gas measured, and shows on the
display the number of the sensor the amount of gas measured and
its origin; the alarm triggered is saved in a memory (Datalogger).
The data stored can be printed (up to maximum 50 events). The
control unit features two levels of alarm: 1st level, pre-alarm. This
data is variable. The technician can modify pre-alarm intervention
for every sensor according to the type of plant to be controlled.
The level can be selected from 5% to 9% of L.E.L. or from 75 to 135
ppm. Main alarm is set from 10-20 % of L.E.L. or 150-300ppm. The
control unit is equipped with a main alarm relay which can be set
with or without Positive Safety Switch to enable further independent
control of a solenoid valve. Finally, the control unit allows the user to
control the actual operation of the sensors coupled.
