Notes:
(1)
Dependent on amplifier
(2)
Dependent on amplifier. Under constant operating conditions. Self-heating of the forcer will cause expansion
in the thrust rod during the initial warm up period. In high duty applications (corresponding to an internal
forcer temperature of 80
o
C) a 1 metre thrust rod will expand typically by 250 µm.
(3)
Maximum error over 1 metre under constant operating conditions.
FORCER ELECTRICAL CONNECTIONS
Connections to the forcer are made via a 15-way high density D-sub male connector which is fitted to the forcer.
The pin-outs are shown in the diagram below and the table shown right.
