NOTICE

notice

The SP300 operates fully automatically with internal auxiliary energy, which is extracted from the process gas. No manual triggering option is provided.

NOTICE

notice

The complete triggering is indicated by a part of the closing piston with o-ring protruding from the SP300. If only part of the closing piston is visible and the o-ring is not visible, partial triggering is carried out. This situation represents a defect in the SP300. It must be corrected in accordance with "Resetting the SP300".
