Protection of Electronics & the Compressor When Arc
Welding
Any arc welding on the skid and/or associated equipment and piping can permanently dam-
age solid-state electronic equipment. Welding can cause immediate failure or reduced life of
such electronic equipment.
Protect the force feed lube flow monitor(s) prior to doing any arc welding (including repair
welding) as follows: Disconnect all connections to the flow monitor including ground, and
remove the batteries. Or completely remove the flow monitor from the compressor.
It is good practice to attach the welding ground clamp as close as possible to the area where
the welding will occur and to use the lowest practical welder output setting. Welding must
not cause a current flow across any compressor bearing surface, including but not limited to
crankshaft and crosshead bearing surfaces.
Electronic-Lubricator Digital No-Flow Timer Switch
(DNFT)
When an Ariel DNFT microprocessor-based switch is supplied, it is used to sense no-flow or
slow-flow conditions in the compressor cylinder lubrication system to facilitate alarm and/or
shutdown. The DNFT also contains an amber light-emitting diode (LED) cycle indicator to
provide a positive visual indication of system operation. The Ariel DNFT includes a proximity
switch. The Ariel DNFT, usually supplied, is factory set for (3) three minutes from no-flow to
alarm/shutdown signal and is not adjustable. Optional programmable models are also avail-
able. Introduced in September of 1996, the DNFT replaced the traditional mechanical no-
flow switch and is optional on all new units. Since its introduction, the DNFT has undergone
