2.2.1
Temperature Limits
The motor temperature has a maximum limit of 248
o
F [120
o
C]. Allowing the temperature to
exceed this limit will permanently damage the motor windings. The maximum oil
temperature limit is 149
o
F [65
o
C].
Observe the operating temperature range limits as presented in Table 1. Do not operate the
unit if the ambient temperature where the unit is located exceeds these limits.
Exceeding these temperatures may result in reduced operational life
or damage to the product.
2.2.2
Pressure Range
The normal operating pressure of the unit is 0 to 500 psi. Avoid operating the unit against the
rudder stops for prolonged periods of time.
2.2.3
Duty Cycle
The HPU100 is designed as an intermittently operated unit for normal steering applications.
High demand applications will over work the motor and cause over heating.
