PROMATRIX SYSTEM

1. Utilization

The switch-modepower supply rack units DPP4004/4012 are meant for the incorporation into 19" rack shelf systems and serve to supplyPA-systeminstallations with the operational voltage of 24 V.

The switch-modepower supplies DPP4004/4012 can be operated as single units, together with thePA-systemPROMATRIX, orbattery-powered,as well as together with the DYNACORDDEM-system.

Caution: It is not permissible to expose this appliance to dripping or splashing water.

2. First Operation

The switch-modepower supply rack units DPP4004/4012 are to be operated on the 230 VAC mains supply. Internally switching the appliances to different voltages is possible (please refer to the paragraph 4: adjusting the mains voltage). Connecting the power supplies is only licit on a accurately installed3-polemains outlet.

The mains outlet connector (6) is meant for convenient connection within rack shelf systems. It is possible to connect other devices to the mains output (6), using a common mains cord. A maximum power consumption of 1 A should not be exceeded.

3. Functions of the DPP4004/4012

The power supply rack units DPP 4004 and 4012 were designed to supply PA-systemswith or without emergency battery power supply with the necessary power. They can also be used to remotely control (on/off) several functions. Managing the switching between mains and battery supply is performed automatically.

Using the mains switch (1) (main switch function) on the front of the appliance, it is possible to turn the system power off completely. To prevent inadvertent erroneous switching, a cover lid can be installed with the switch being ion its ON-position.

When the switch is set to OFF, all outputs are without current and the MAINS (2) and BATTERY (3) LEDs are not lit. With the mains switch being engaged, the internal 24 V power supply is provided with mains voltage. At the same time, the mains output connector on the rear of the appliance gets mains supply (max. 1 A), allowing the connection of external low-levelpower consumers (tape decks, etc.). With the mains switch being engaged and when the appliance is correctly connected and the mains is present, theMAINS-LEDwill light. Correspondingly, theBATTERY-LEDis lit when a battery power source providing 24 V is correctly connected to the BATTERY IN connectors – (12) and (13) – and with the mains switch being engaged.

The output voltage of the internal power supply is present at the DIRECT OUT (9) connector. With the DPP 4004 this connector’s maximum power handling capacity is 4 A; the DPP 4012 provides 12 A. The output offers internal short-circuitprotection and it can be operated without load. It also serves to use the appliance as plain power supply – without battery supply and without remote control.

The output SWITCHED OUT (16) is meant for the connection of the DPM 4000 or other external devices that need non-interruptedemergency power supply. With the DPP 4004 this connector’s maximum power handling capacity is 4 A; the DPP 4012 provides 12 A. The output offers internalshort-circuitprotection and it can be operated without load. Usually, this output is connected to the internalswitch-modepower supply, so that the connected load is supplied with the needed voltage. In case of temporarily insufficient mains supply, power failure, malfunctioning of theswitch-modepower supply or thermal overload of the DPP 40xx, the SWITCHED OUT (16) is switched to battery supply (when present) within fractions of a second, providing gapless power supply to the connected devices. When the mains is present again or after solving the problem that caused the malfunction, the appliance automatically returns with a delay of 600 ms to mains operation. If there is no battery present during the occurrence of a mains complication, the DPP 40xx behave as if the front mains switch has been switched off; except for the fact that the MAINS LED is still lit.

The output MODULES OUT (14) is meant for the connection of devices (relay-fields,alarm-devices,voice reproduction, etc.) that can be switched off during a power outage – during which time thePA-systemshould operate in thestand-bymode. Switching off unnecessary devices during the occurrence of a power failure is preferable, otherwise the battery is unnecessarily strained. The output employs a “softstart” function that controls the initial current inrush, preventing the main supply from interference by possible

15

DYNACORD

PROMATRIX SYSTEM

capacitive loads connected. This output is controlled by the inputs ON/OFF (TOGGLE) (pin 1 of the remote control connector) or ON/OFF (MODULES) (pin 2). If the ON/OFF (MODULES) input is connected to the ground potential, the MODULES OUT output is constantly activated; otherwise it is constantly deactivated. The input is controlled from the DPM 4000 or from an alarm or gong signal module.

The input ON/OFF (TOGGLE) can be used for installations, where the PA-systemhas to be switched “on/off” via remote control (e. g. systems that includeDEM-modules).A ground potential contact of the input switches the system “on”, another one switches the system “off”. The ON/OFF (MODULES) input’s priority in the “on” state overrides ON/OFF (TOGGLE). The ON/OFF (TOGGLE) condition is also stored for the time of power failure. Switching the appliance’s mains switch off always sets theTOGGLE-stateto “off” as well. When utilizing the ON/OFF (TOGGLE) and ON/OFF (MODULES), it is important to remember that thepin-assignmentof the floating inputs corresponds to the illustration in chapter 5 (figure 2).

The ON/OFF (TOGGLE) function is deactivated when the appliance is shipped from the factory. To activate the function, the appliance has to be separated from the mains and the internal jumper has to be set to “open”.

This input can also be used to detect whether another phase failed. The corresponding jumper must be in place. When short-circuitingthe contact and ground, the appliance reacts as if its own mains failed. In case externalphase-monitoringis not wanted, leave this input unused.

The control output (pin 4) MAINS REMOTE ON on the REMOTE socket (10) carries ground potential when the output MODULES OUT (14) is switched on and with the mains supply being constantly present. This output can be used to switch remotely controllable power amplifiers of the PROMATRIX and the DEM Series to mains supply.

The control output (pin 5) BATTERY REMOTE ON on the REMOTE socket (10) carries ground potential when the output MODULES OUT (14) is switched on and with the mains supply being unstable. This output can be used to switch remotely controllable power amplifiers of the PROMATRIX and the DEM Series to battery supply.

The control output (pin 6) POWER FAIL OUT on the REMOTE socket (10) signals the loss of the mains supply (main under voltage, mains failure, temperature overload with insufficient output voltage of the switch-modepower supply). An output voltage of +24 V indicates that the mains supply is present and stable. The output’s internal resistance is 1 kΩ. It is meant for the connection of the DPM 4000, indicating mains failure conditions.

The control output (pin 7) DELAY OUT on the REMOTE socket (10) is switched to +24 V with a delay of approximately 6 seconds after activating the output MODULES OUT. This function can be used to signal that the installation is ready for operation, after booting the system. In installations incorporating DEM-modules,the output provides the “release” function.

Procedures with occurring mains failure

In a standard application with mains and emergency battery supply, the outputs SWITCHED OUT and MODULES OUT are switched to battery supply when a mains failure occurs. Despite, POWER FAIL OUT signals the loss of mains power and the connected power amplifiers are switched from mains supply to battery supply via the outputs MAINS REMOTE ON and BATTERY REMOTE ON. When the mains returns, these functions are reversed after a delay of approximately 600 ms.

In case the power is gone for a longer period of time, the battery serves as emergency power supply until the cut-offvoltage of 21 V is reached. When declining that threshold for the first time, all outputs are being switched off. After the mains being present and stable again, the outputs are switched on again. This preventsover-dischargingthe battery.

4. Mains Voltage Selection (only to be carried out by a qualified service technician)

After adjusting the mains voltage, operating the DPP 4004/4012 power supplies with 115 V is also possible.

The adjustment has to be carried out before the operation:

-Remove the cover plate.

-Insert the flat wire bridge on the printed board assembly 86245 into the 115V~ position (red conductor).

-With the DPP 4004 additional switching of a switch-modepower supply is necessary. The correspondent switch is located inside theswitch-modepower supply (see yellow label). Remove

the front panel (4 screws). Using a suitable screwdriver (size 1), the mains voltage selector switch which is located behind the perforated coverage – has to be set to the 115V~ position.

A silvery label stating different voltages is located on the right inside of the enclosure. After switching the appliance to 115V operation, the corresponding label has to be removed and attached to the rear panel, so that it covers the imprinted marking 230V~ below the mains connector.

The following only applies to the DPP4012:

Exchanging the mains fuses to operate the appliance with 115 V ~ AC:

-Replace the mains fuse (T2,5A/H for 230 V operation) located in the fuse socket (5) with a T5A-typefuse. The label on the rear panel T2,5A/H which is located below the fuse socket (5) has to be replaced by theT5A-label.

Lock the top cover plate and the front panel in place.
