Environment
Although ruggedly constructed to meet the normal
environmental requirements, it is important that
there is a free flow of air at the front and rear to
dissipate the heat produced during operation.
Installations should be designed to allow for this.
If servicing is to be carried out in situ allow space
(approximately 165mm) at the rear for the rear
panel to be hinged down. The power supply is also
withdrawn from the rear.
If the unit(s) is to be rack mounted, first open the
front panel; details are given in Section 8. The
fixing "ears" behind the panel will be revealed and
the unit can be mounted in the rack. Refit the front
panel.
Remote Control
The unit may be controlled via the RollCall remote
control system from an active front panel.
It may also be controlled via RS422 serial link. A
remote control panel can be supplied or the user
may use their own control system.
The serial protocol is freely available on request
from Snell & Wilcox.
For details of the menu system see Section 4, and
for details of the RollCall system consult the
Modular System Operation manual.
Control may also be via the GPI (if fitted) which
provides 12 inputs and outputs.
For more details see page 3.5
