Paramount ME User’s Guide

Cold Temperature Operation
The amount of torque required to turn the Paramount ME’s worm-gear interface increases
as the temperature decreases. Therefore, the maximum slew rate for the right ascension
axis should be reduced when the Paramount ME is operated in cold temperatures (less
than 32º F or 0º C). Reducing the maximum slew rate effectively increases the
servomotor’s maximum torque so that the mount can operate normally.
Software Bisque recommends setting the right ascension slew rate to 50-65 percent under
these conditions. See the “XMKS 4000 Options TabX” section on page X74X for details about
setting the Paramount ME’s maximum slew rate based on the ambient temperature. For
extremely cold temperature operation, the Paramount ME’s acceleration rate may also
need to be reduced.
See “XTroubleshooting Mount OperationX” for additional cold temperature operation issues.
Troubleshooting Mount Operation
TheSky6 Professional
Edition cannot
communicate with the
Paramount ME.
Communication between a personal computer and hardware
device requires that the software and hardware be properly
configured. If you cannot establish a link to the telescope, we
recommend trying the following:
1. Check the cables to the serial communications port (COM).
They must be securely plugged in at both ends.
2. Check the communications port with a different device. For
example, connect a different serial device to the port and
ensure it is working.
3. Make sure the software settings are correct for the
communications device (TheSky6 Professional Edition’s
Telescope > Setup > Settings > Telescope Setup dialog
box).
The Paramount ME
emits continuous,
successive, high-pitch
“beeps” shortly after
startup and will not
slew.
Check that the balance knobs are adjusted properly
(page X43X). If the balance knobs are too tight, then the
worm is forced against the gear, and the mount will not
slew. Also read “XSounds Emitted During Mount
Initialization and OperationX” on page X35X for more
information.
Check the mount balance in both axes. If the
Paramount ME stalls or sounds labored while slewing,
check to make sure both axes are properly balanced.
Balance becomes more critical with heavier loads. While
the control system has sufficient torque to lift heavy
loads, tracking performance and slewing may suffer
when the payload is greatly out of balance.
