2 Safety
2.6 Risk Sources
The following risk sources may be associated with the operation of the dispensing
station:
Failure to comply with these instructions could result in material
damage and death or serious injury of humans.
– Depending on the pump capacity setting, product will be fed at a pressure of up to
40 bar. Product escaping from defective tubing or components may result in
injuries and material damage due to splashing product.
– During initial start-up and subsequent transfer of product to refill the reservoir, air
bubbles trapped within the product may cause uncontrolled squirting from the
meter-mix dispense gun. Tubes should always be depressurised completely before
starting operation.
– Wear suitable protective clothing whenever processing chemical or corrosive
materials or products, which pose potential health risks. Comply with safety
regulations and observe the manufacturer’s instructions. Provide adequate
ventilation or exhaust system. Take special precautionary measures whenever
hazardous materials are involved, provide e.g. an eyewash station in case of
corrosive chemicals.
– Only staff possessing special skills and experience must be allowed to handle
pneumatic, hydraulic and electrical equipment.
When the pump unit is lowered onto the product container there is a
risk of fingers getting crushed. An appropriate safety label is affixed to
the dispensing station!
2.7 Safety Systems
The electronic pump control system monitors
– The operating pressure,
– Product availability in the two containers, and
– Electrical connection of the two pump motors.
If
– Operating pressure exceeds 40 bar,
– There is no product left in one or both containers,
– One of the two electrical pump motor terminals is not connected,
the dispensing station is shut off and a relevant error message is displayed. The
error must be corrected and the fault signal reset to resume operation.
