Cadac consoles are designed to allow th e use of two independent power supply systems in a redundant configuration – “main” and “backup ”. Both sets of power supply units are used to power the console system so that under normal conditions, the ‘loa d’ is sh ar ed b etw e en th e “ m ai n” a nd “ bac ku p” PS U’s. I f a f a ul t o cc ur s in on e o f t he power units ( c ausing it to ‘shut-down’), the remaining power unit will power the console.

For smaller B-Type consoles (consuming no more than 44A), it is possible to use the 8400 PSU. See 1. 3. 7 8 400 switch-mode power supp ly uni t.

One ±18V PSU and one +13V/+48V PSU is referred to as a “PSU System”.

Designate one pair of power supply units as “SYSTEM 1" and the other as “SYSTEM 2". PSU System 1 and PSU System 2 should be connected to the same on the same ‘spur’, wherever possible. In situations where it is necessary to provide a separate ‘feed’ to each PSU system pair, make sure that the cable lengths are the same. This is to minimize any induced a.c. power input noise by ensuring that the “EARTH IMPEDANCE” is the same for both PSU systems.

The a.c.-input connectors on each power supply unit have three conductors: ‘LIVE’ (brown), ‘NEUTRAL’ (blue) and ‘EARTH’ (yellow/green). For safety and electromagnetic compatibility considerations, it is essential that the ‘EARTH’ conductor is connected on all PSUs continuous c ircuit to the “zero-signal reference potential” point in t he building. The ZSRP point in a building is usually found near the place where the a.c. ‘mains’ supply enters the building (often referred to as the “MAIN GROUND REFERENCE EARTH ELECTRODE SYSTEM”). The basic concept for correct a.c. mains wiring distribution is shown in figure 1-1. If you need further information about this complex subject, please refer to “Grounding Systems and their Implementation” by Charles Atkinson and Philip Giddins published in the AES Journal Vol. 43, No. 6 – June 1995. The grounding scheme in CADAC consoles is designed to meet the rigorous EEC

If replacing a switch-mode power supply unit is required, please note the following:

Make sure that the power supply s ystem’s power switches are in t he position

■■■■

OFF and disconnected from the mains.

The work should only be carried out by a suitably qualified electrician.

■■■■

Be careful to observe corr ect polarity when connecting the new PSU.

■■■■

Note that a console must never have one voltage without the other, f or exam ple

■■■■

+18V must never be fed into the console without -18V.

When switching the power supply system back ON after replacement has taken place, make sure that both LEDs on the front of the PSU-system come on. If only one LED comes on, let go of the ON push-button immediately. Failure to do so may lead to fire hazar d and major damage to th e console.

NO TE:

Under no circumstances, should the 8019 or 8020 PSU be used without a SAFETY EARTH connection. Failure to follow this instruction is both a fire and safety hazard.

Connection to a 3-phase outlet is required on sites where the system voltage between any one of the phases and neutral is 100-127V and the voltage between any two of the phases is 20 0-240V. Before connecting to any 3-phase outlet, please refer to a qualified electricia n who understands your particular installation and the local safety and wiring regulations. Under no circumstances should the 8019 and 8020 switch-mode power supply units be operated without the green/yellow safety earth conductor connected to the building safety earth conductor system. Each power unit is equipped with an input supply filter whose reference ground conductor is the chassis. Failure to connect the green/yellow safety earth conductor to the correct eart h/ground building reference is a safety and fire hazard.

1. Connect the LIVE (Brown) conductor on the “system 1” 8019 unit to the phase 1 (L1, RED) terminal on the 3-phase power outlet connecto r.

2. Connect the NEUTRAL (Blue) conductor on the “system 1” 8019 unit and the LIVE (Brown) conductor on the “system 1” 8020 unit to the Phase 2 (L2, YELLOW) terminal on the 3-phase power outlet connector.

Each 801 9 and 8 02 0 s w it ch- mod e p o we r supp ly is fi t ted wi th a f ron t p an el mo un ted 9 way ‘D-type’ connector. This connector is labelled “Connections for Remote Start”. You may connect a single remote start switch to each unit, have one switch start a “system” pair, or wire up a single switch to start “system 1” and “system 2” all at the same time.

Fig 1-5 applies to 8019 and 8020 PSUs up to serial number 34949 and shows the circuit for starting up a “s ystem” pair with a single switch. This has pro ved to be the most popular method of connecting the remote start facility. This circuit can easily be extended to provide a single switch remote four all four PSUs if required.

For 8019 and 8020 PSUs from serial number 34950 onwards, see fig 1-6 and 1-7.

NOTE:

The remote must be a ‘momentary’ type. You will need a two-pole switch for a

On each power s upply, tu rn all AC input switches to the ON-position.

Start the ±18 V an d 13V/ 4 8V PSU s (in one PSU syst em) simu lt an eo us ly, by pressing and holding the START-buttons until you hear the relay click. The CCM will cycle through its self-test routines and any Master Mute swit ches previously selected will be set ON, thus protecting external equipment from possible DC pu lses when the ±18V PSUs ar e sta r ted.

Repeat for PSU system 2. If you cannot start the PSUs simultaneously, start the 13V/ 48V first. However, do NOT operate the console for long periods without all power lines on.
