47-602 F10 and F50 Flow Switches
11
NOTE: As a matter of good practice, spare switches should be kept
on hand at all times.
3.1.3 Inspect Entire Unit Periodically
Increase and decrease liquid flow through the pipeline to
check for switch contact and reset.
3.2
What To Avoid
1. NEVER leave switch housing cover off the control longer
than necessary to make routine inspection.
2. NEVER place a jumper wire across terminals to cut-out
the control. If a jumper is necessary for test purposes, be
certain it is removed before placing control into service.
3. NEVER attempt to make adjustments or replace switches
without reading instructions carefully. Certain adjustments
provided for in flow switches should not be attempted in
the field. When in doubt, consult the factory or your local
representative.
4. NEVER use lubricants on pivots of switch mechanisms.
A sufficient amount of lubricant has been applied at the
factory to ensure a lifetime of service. Further lubrication
is unnecessary, and will only tend to attract dust and dirt
which can interfere with mechanism operation.
