User Manual
Rev. 1.0 - 26/03/04
The management software of the HC5-10 is based on a menu system.
The user can navigate through the menu system using four buttons, ESC, move LEFT/
UP, move RIGHT/DOWN and ENTER. A fifth button is used to reset the alarm counters,
if any alarm has been triggered before.
The state of the machine comes indicated from nine LEDs present on the frontal
panel.
A switch on the front panel allows to select the LOCAL or REMOTE working mode:
•
LOCAL mode allows to control the machine using the buttons on the front panel,
while remote control (that is using the telemetry connector) is disabled;
•
In REMOTE mode, remote control is enabled, while the buttons on the front panel
can be used only to read parameters and not to change them
The LOCAL working mode is signalled by a yellow LED on the front panel being lit.
The different working parameters are made available for the remote control
applications on the telemetry connector, as voltage levels that are proportional to the
value of the parameter under consideration. Digital output signals related to alarms
or warnings are also present on the connector, together with the digital input like ON/
OFF switching or alarms reset.
The HC5 can be connected to the exciter of the transmitter using a “interlock” cable,
so that it is possible for it to deactivate RF power emission in case of misfunctioning
of the transmitting system. An analogous effect can be reached also in case the
exciter misses the interlock functionality, connecting the mains supply of the exciter
to the auxiliary mains plug of the HC5-10 “AUX OUT AC LINE”. This plug is in fact
opened using a relay under the same conditions that cause the activation of the
interlock.
