6.1.3
Remote Pressure Compensator, P-RNN
This control option functions the same as the Pressure Comp. Only option discussed in
Section 6.1.1
, except that the
compensator signal comes from a remote system component, supplied by the system designer.
6.1.3.1
Function
Remote pressure compensation adds a compensator set point
adjuster for the pump at a remote location. Please note a pressure
set point adjuster still remains on the pump, and should be
adjusted to a pressure 200 psi higher than the anticipated
maximum remote pressure set point.
The system designer provides the following for a remote
compensator circuit:
•
A remote pressure compensator valve with a flowrate of
approximately 0.25 GPM. The inlet port of the remote
pressure compensator valve is plumbed to the LS/RP Port on
the Valve Plate, as shown in
For more information on the circuit, please see the circuit diagram
in
Section 6.1.3.5
Additionally, 2 values are chosen and adjusted in the circuit:
P
remote comp
Remote Compensator Pressure, set in the remote compensator valve
P
comp
Compensator Pressure, set 200 psi above the setting of
P
remote comp
, in the on-board Pres. Comp. Adjuster
6.1.3.2
How to Adjust
P
remote comp
is adjusted using the instructions for the remote compensator valve, chosen by the system designer.
P
comp
is adjusted using the PC Adjuster, mounted on the Control Block as shown in
Adjuster:
3/16 in. Internal Hex
Range:
500
–
5,000 psi [13.8 to 345 bar]
Rate:
485 psi [33.4 bar] per turn
6.1.3.3
Response Time
The control’s response time will be determined by the remote compensator circuit supplied by the system designer.
6.1.3.4
Required Orifice
A pilot orifice is required for proper function of a remote
compensator circuit. The pilot orifice is installed in OP16, under
the Function Port, as shown in
