Safety at environment- 

In AUTO mode, whenever PUMP STARTS at LOW Level thru Level Switch contact, but, media / application is not comes to the tank due to reasons like solenoid valve is not OPEN / float leakage etc…on that case, provide one additional relay for hooter along with DRY RUN indication. This relay may activate according to IC Programmable timer

The above logical operated controller may come in MS POWDER COATED PANEL.

Note : Mainly using at this type of controlling system nearer at Solvent applications / hazardous areas.

Flame Proof Auto / Manual Controller Operational Manual :

High Level - PUMP / Solenoid Valve OFF
Low Level - PUMP / Solenoid Valve OFF

Might to give input voltage supply of 230VAC. For Auto & Manual, provided separate push buttons for selecting the mode.
