Product Code, p. 12 ➜ The immersion lock can be seen at the yellow indicator ring on the drive unit of the SensoGate WA130H. If the yellow indicator ring is missing, the safeguard func- tion is not available. A mechanical lock prevents the SensoGate WA130H with- out a mounted solid-electrolyte sensor from being moved into the process position (PROCESS limit position). -
Page 7: Residual Risks
Safety Accessories, p. 8 ➜ Operating the SensoGate WA130H without a retainer or locking clamp is at the risk of the operating company. The operating company must take action to rule out the possibility of the screw joint cou- pling nut accidentally loosening. -
Page 8: Safety Accessories
The retainer clamp prevents the coupling nut of the Ingold socket (25 mm) screw joint from accidentally coming loose. The wires of the retainer clamp connect the SensoGate WA130H to the cus- tomer’s process port. A locking lug on the retainer clamp engages in the groove of the coupling nut (form‑fit). -
