System Monitoring
In a series progressive system, the primary and sec -
ondary CSP valves can be connected with high pres -
sure hoses so every outlet is linked together.
If one plunger in one of the CSP valves is not working,
lubricant is no longer supplied to any of the outlets.
If one of the secondary CSP valves is blocked, then the
primary CSP valve is blocked and the entire system
installed downstream from the pump stops working.
A cycle indicator makes it possible to monitor the oper -
ation of the entire system.
Cycle Indicator
A CSP valve can be equipped with a cycle indicator pin.
The cycle indicator is connected to the plunger and
moves back and forth during plunger movement and as
lubricant is distributed.
NOTE : A micro limit switch/proximity switch/sensor can
be installed to the cycle indicator to monitor the system
electronically.
Electric System Monitoring
A system can be set up to use an electronic controller
or to use a pump with a built in controller. A
micro-limit/proximity switch/sensor can be installed to
the cycle indicator on the CSP block and connected to
the electronic controller. Together they control the
pump operating time by counting cycles until the preset
number of cycles has occurred.
The system can be set up to indicate a fault if the preset
run time expires before the preset number of cycles are
counted.
Proximity Switch Kits
NOTE: Available only for CSP valves with an indicator
pin.
To install the proximity switch kit in the system, select
the correct adapter from the package. Each package
contains two types of adapters. The cylindrical adapter
fits with the series A CSP valve (F
IG
. 2), and the rectan -
gular adapter fits with the series B CSP valve (F
IG
. 3).
NOTE : Use of the wrong adapter will cause the system
to fail.
