WARNING:
Corrosive components can endanger operation
▸
Check all parts, especially those made of stainless steel, for corrosion and exchange
these parts as necessary.
Corrosion on device parts can impair safety with regard to explosion protection, leak
tightness and pressure.
NOTE:
Risk of damage to the TRANSIC151LP through dust or humidity
▸
Only open the TRANSIC151LP in a dry environment free from dust.
CAUTION:
Plant-specific hazards during maintenance work
▸
Observe local regulations with regard to plant-specific protective equipment during
maintenance work.
NOTE:
SICK recommends cleaning the optical components when the signal
strength is below 80%.
