3.1 OVERVIEW
The APS (Advanced Power System) is a power distribution unit with a 3 phase mains input
(single phase input is possible) and either 6 or 12 single phase outputs depending upon the
model.
3.2 SWITCH ON
The outputs of the APS are always switched on sequentially to minimise surge current. This
is known as a “staggered switch on”. The time delay between channels switching on can be
set using the touch screen.
The outputs can be switched on via the following methods:
 Whenever DMX is detected on the APS DMX input.
 Via a remote switch plugged into to the DMX input. See section 2.4.4.
 In “Stand alone” mode, whenever power is present on the input. See section 4.7.
 Manual switch on via the touch screen (with user lock out). See section 4.6.
 Via RDM. See section 5.2.
 Emergency mode. See section 6.2.
3.3 SWITCH OFF
The outputs of the APS are switched off via the following methods:
 When DMX is no longer present on the APS input. A delay time can be set using the
touch screen.
 Via a remote switch plugged into to the DMX input. See section 2.4.42.4.4.
 Manual switch off via the touch screen (with user lock out) See section 4.6.
 Via RDM. See section 5.2.
3.4 FRONT PANEL
The front panel contains the RCBO (Residual Current Breaker with Overcurrent) circuit
breakers for each output, the touch screen and the DMX/GPI input and output and a SD
card slot. The number below each circuit breaker shows which input phase feeds that output
channel.
