•
ALWAYS OFF. The channel cannot be turned on by UNITOUR (
except in “Emergency
Mode”). See section 4. Warning, do not rely on this setting to isolate the power.
•
ALWAYS ON. The channel can only be switched off by its channel RCBO (circuit
breaker).
•
DIMMER mode. The channel utilizes pulse transformer circuitry which allows it to
control difficult loads including neon, motors and low wattage lamps as well LEDs
and convention incandescent lamps. This mode is not available on USMT switch
modules.
The UNITOUR is all about safety for both the operator and the equipment attached to it. This
protection includes dropped neutral protection (the rack will shut down in the event of a
dropped neutral until the fault is rectified), configurable over/under voltage protection,
individual 30mA RCBO (Residual Current Breaker with Over-current) per output and
staggered channel start for
“Auto Power” and “Always On” channels.
In addition, nuisance circuit breaker tripping is overcome by using ZCSS (Zero Cross Soft
Start) that switches on the relay as the mains voltage passes through the zero point of the
sine wave.
The UNITOUR
’s clever software provides real-time voltage and current monitoring per phase,
as well as load current (RMS and Peak) and earth leakage current (RMS and Peak) monitoring
per channel. The peak readings are logged with a time/date stamp, helping to identify the
cause of a tripped breaker. Warning thresholds can be set to alert you when each channels
earth leakage current or load current are approaching limits. This can help you to take
measures to prevent a loss of power by redistributing loads or replacing faulty equipment
before the breaker trips.
On large complex show systems, it is vitally important to monitor what is happening within your
system, from anywhere. UNITOUR solves this issue and can be configured and interrogated
locally on the built-in large touchscreen or r
emotely via LSC’s HOUSTON X monitoring and
configuration software.
Pre-show, the UNITOUR racks can be configured without connecting them to 3-phase power.
Just connect all the racks via a PoE Ethernet switch which powers the UNITOUR Head Module
allowing local or network configuration.
An optional SMS service allows the UNITOUR to send a text message directly to a technician
when specified alarms or warnings are triggered. Future feature.
