4.3.1 Setting Position Limits
Limits must be set before operating. The actuator will not operate until limits are set.
NOTE:
A passcode is not needed for the initial position limit settings. However, any limit
setting changes required after initialization requires a passcode and are changed
via the
“CHANGE SETTINGS”
mode. See
Section 5.5.3, Set Valve Travel Limits.
CAUTION:
It is recommended that the final valve position be set using the handwheel
while setting the limits to prevent valve damage.
There are two different routines for setting limits. Initial limit settings can be set as
described in
Section 2, Quick Start
. Limit settings can be changed as described in
Section 5.5.3, Set Valve Travel Limits
.
Once the limits have been set, check the settings as follows.
