PCO-818 Automatic Changeover Unit
As your GenFlex system grows, the PCO-818 stands ready to
grow with you. Engineered to provide complete sync
system reliability in a compact, economical package,
its advanced modular design provides flexibility never
before available in an Automatic Changeover unit.
Combined with the SPG-812, the PCO-818 offers the
best performance and reliability available today. It’s
basic function is to monitor an installation’s primary
sync generator and automatically switch to a backup generator in the event of a failure to the primary.
Modular design offers several advantages over traditional automatic changeover units: Monitor only the signals used by
the system: no need to pay for monitoring capability that isn’t required by the system. Install only the modules you need
now–add more later. Each module is matched to it’s signal: this allows them to accurately monitor pulses of various
amplitudes and widths. It also allows analog and digital signal monitoring in the same chassis. Since the PCO-818 and the
SPG-812 Sync Generator share a common chassis, modules may be interchanged between units. For example, a TV station
may use a single SPG-812 generator with a backup blackburst generator installed in the changeover chassis. In addition,
the PCO-818 is designed such that AC mains failure will not erase the memory of it’s last generator selection. Dual-coil
latching relays provide a reliable signal path even if power is lost to the PCO-818. Meanwhile, its power supply features a
“universal” voltage input range of 85v to 260v AC. In extreme conditions, the PCO-818 would be the last unit to shut down
in the event of an AC mains failure. Bi-color LEDs provide instant status indication for each signal in your system. If a
particular signal isn’t in use, the LED can be easily de-selected (dark) rather than produce a false failure (red) indication. A
“Manual/Automatic” switch allows you to override the automatic changeover function and select either generator in the
system. The PCO-818 is a chassis, power supply and motherboard only. You choose the modules to meet your requirements.
PCA-819 Remote Changeover Alarm
An add-on to the PCO-818 changeover system, the
PCA-819 Remote Changeover Alarm is engineered to
provide a convenient way to monitor changeover,
due to loss of signal, at a remote location. Bi-color
LED’s provide a visual indication of the Changeover
Frame status. Additionally, an audible alarm sounds
to indicate an alarm condition. And to provide even
more flexibility, isolated relay contacts are provided so the user can control other equipment or alarms in the event of a
loss of signal at the Changeover Frame.
Front panel switches allow the user to disable the alarm signal from either, or both, generator banks, and also mute the
audible alarm. Whenever a loss of signal occurs on any of the various changeover modules in the PCO-818, an alarm
signal is generated and the PCA-819 shows the alarm condition on the front panel. The PCA-819 is housed in a rugged 1RU
rackmount enclosure, and can be powered from120 or 240v AC.
