Grounding monitoring device
Series 8146/5075, Series 8150/5-V75
10.2 Indications
The corresponding indicator lamps on the device indicate the operating conditions of the
device and the line fault states (also refer to chapter "Function and device design").
10.3 Troubleshooting
Observe the following troubleshooting plan for troubleshooting:
If the error cannot be eliminated using the mentioned procedures:
• Contact R. STAHL Schaltgeräte GmbH.
For fast processing, have the following information ready:
• Type and serial number of the device
• Purchase information
• Error description
• Intended use (in particular input / output wiring)
If tank containers are used, pay attention to rubber buffers which may
separate the tank from the frame.
The connection to every metal object would lead to a signalling of sufficient
grounding. Therefore, connect the clamp only to the object to be grounded or
to the insulated suspension point on the enclosure.
