Installation and Maintenance Manual, Compact CA
There are three distinct cases:
Case 1:
The motor works in braking mode. Required
charge pressure at the inlet port is according
to diagram below.
Case 2:
The motor works in driving mode only. Required
back pressure at the outlet port corresponds to
30% of value given in diagram below, but may
not be lower than bar (9 psi).
Case 3:
The motor is used with -speed valve. Required
charge pressure at inlet port for valve is
according to AC-3.1 Accessories.
The hydraulic system must be such that the
motor will recieve sufficient charge pres-
sure at the low-pressure port. This app-
lies to all types of installations.
Note:
The diagram is valid for 1 bar (15 psi) case pressure. With increasing case pressure the charge
pressure must be increased accordingly. The graph is valid when 4 ports are used. Max casing
pressure is 3 bar (43,5 psi)(for 1% of the operation time evenly divided, pressure peaks of max 5
seconds upto 8 bar (116 psi) is allowed). Max permitted case pressure at stand-still is 8 bar (116
psi).
