Notes:
1. The associated apparatus must be a linear source or a FISCO power supply.
2. Sensor 1 may be simple apparatus or intrinsically safe apparatus.
3. When accessing the display window or other non-metallic parts of the enclosure of FLXA21,
take the following measures to minimize the risk of explosion from electrostatic discharges, in
addition to avoiding any actions that cause the generation of electrostatic charges, such as
rubbing with a dry cloth.
To avoid electrostatic charge on the operator,
- Earth the operator through a wrist-strap, or
- Operate FLXA21 on the conductive floors, wearing anti-static work clothes and electrostatic
safety shoes, or
- Neutralize the operator and FLXA21 by a static elimination bar which has a metal part
earthed through resistor from 100k
In case that those measures cannot be taken or static electricity cannot be suppressed, bring a
gas detector and make sure there is no ignition capable atmosphere around FLXA21 before the
operation.
