The basic devices SITOP PSU8600 are primary-clocked power supplies for connection to 3phase AC line supplies. An electronically regulated DC voltage that can be set via a potentiometer is available at the output of the devices. The device output is isolated, no-load and short-circuit proof and has an electronic overload trip - or alternatively overload current limiting (constant current), which can be set using an additional potentiometer. The device output can be switched-on and switched-off using a button.

LEDs signal the operating state of the device as well as the output. The electronic overload shutdown is reset using the reset input and the button of the output. Additional, special functions of the devices can be activated using selector switches (DIP).

The device output can be controlled, operating and diagnostics data transferred and externally visualized or processed via the two integrated industrial Ethernet/PROFINET ports. An integrated web server allows authorized users to read and write data remotely via a web browser. Further, an OPC UA server is integrated in the devices (Open Platform Communications Unified Architecture). This facilitates non-proprietary communication in automation systems.

The functionality of the basic devices can be expanded using supplementary modules. There are expansion modules to increase the number of outputs, and buffer modules to extend the internal device power failure buffer time.

2.2 Description of the expansion modules

Using a SITOP CNX8600 expansion module, the number of system outputs can be increased, however, not the maximum output power of the basic device. The expansion modules have, just like the basic device, a potentiometer for setting, and buttons to switchon and switch-off the relevant output. LEDs signal the operating states of the expansion module as well as the individual outputs. A maximum of four expansion modules can be used for each basic device. The connection to the basic device or to the adjacent module is established using an integrated connecting plug.

2.3 Description of the buffer modules

A buffer module SITOP BUF8600 allows the buffer time to be extended when the power fails. An LED is used to signal the operating state of the buffer module. A maximum of two buffer modules can be used for each basic unit. The connection to the basic unit or to the adjacent module is established using an integrated connecting plug.

For brief power failures, the outputs of the power supply system are supplied without interruption using the energy stored in the buffer module.

There are two BUF8600 buffer module versions available: Buffer modules with electrolytic capacitors and buffer modules with double-layer capacitors.

% overload capability for 5 s/min (Extra-Power) and 300% for 25 ms (Power Boost) are

supported.

When using a buffer module with double-layer capacitors, the following additional functions are available:

If a PC is operated on the PSU8600 power supply system, when the power fails, then this must be run down in plenty of time before the buffer time expires in order to avoid data being lost. If the supply voltage returns after the shutdown has already started, the buffer mode is exited and the power supply resumes normal operation. However, the PC is run down completely. If the PC does not have an ON/OFF-switch, then it can only be rebooted by switching off the power supply and switching it on again.

When using a buffer module with double-layer capacitors, the "Enable short-time interruption at output 1" function is used to activate the brief interruption of the voltage at output 1 when the supply voltage returns. However, selection and parameterization are only possible when appropriately configured (STEP 7, OPC UA server, web server).

2.3 Description of the buffer modules

In order to increase the service life of the buffer modules with a double-layer capacitors, these can be operated in the "Longlife" mode with reduced buffer capacity. When the buffer module is completely charged (LED " lights green) power failures of 3 s up to a maximum of 8 s can be buffered with a load current of 40 A. However, the "Longlife" mode is only possible when appropriately configured (STEP 7, OPC UA server, web server).

In the ELECTRONIC SHUTDOWN operating mode:

• Output switched off to due overload

Other possible causes:

• No output voltage (e.g. as there is no supply voltage)

• Basic unit and supplementary modules shut down due

to overtemperature

• Basic unit and supplementary modules shut down due to phase dissymmetry or failure

• Basic unit has limited power output and expansion mod- ule shut down due to system overload

• Output shut down due to overtemperature

• Communication error between the basic unit and sup-

Buffer mode of the SITOP BUF8600 buffer module with double-layer capacitors can be prevented using control contact ON (terminals "X1" and "X2"), if a scheduled shutdown of the power supply is planned (e.g. for maintenance, period of no operation, end of work/shift). This avoids unnecessarily discharging the buffer module.

Deactivation via the control contact is effective for all of the SITOP BUF8600 buffer modules in the system.

Buffer active, system is buffered when the power fails.

The signaling contact "Sufficient buffer readiness" "READY" is in the form of a relay contact (NO contact, terminals "13" and "14"), and signals that the buffer module is charged to x % (factory setting: 85 %) and is therefore ready for buffering. The threshold value can be freely parameterized via Industrial Ethernet/PROFINET interface.

For two BUF8600 buffer modules with double-layer capacitors in the system, the threshold that is set refers to the sum of the charged energy storage devices in both buffer modules. The signal "Sufficient buffer readiness" refers exclusively to the SITOP BUF8600 buffer modules with double-layer capacitors in the system.

For two SITOP BUF8600 buffer modules with double-layer capacitors in the system, both modules simultaneously signal buffer mode using the signaling contact. As a consequence, it is sufficient to wire one of the two contacts. The signal "Buffer mode" refers exclusively to the SITOP BUF8600 buffer modules with double-layer capacitors in the system.

3.3 Overload shutdown and carrying out a reset

For the device output, in the ELECTRONIC SHUTDOWN mode, overload is permitted for a defined time. The output is electronically shut down after the limit value has been exceeded (see the following diagram).

An output current up to the value set using the current potentiometer is continuously permissible (LED "ON/OFF/RST" of the output is lit green).

In the range 101...149 % of the setting value of the current potentiometer, an overload current is permissible for 5 seconds (LED "ON/OFF/RST" of the output flashes green), then the output is electronically shut down (LED "ON/OFF/RST" of the output is lit red).

In the range > 149 % of the setting value of the current potentiometer, the current is limited to 150 %, after approx. 200 ms the output is electronically shut down (LED "ON/OFF/RST" of the output is lit red).

Using a reset, the output that has been automatically shut down can be switched-on again after a wait time of 5 seconds (LED "ON/OFF/RST" of the output flashes red).

Two overload responses can be defined for output 1:

● In the ELECTRONIC SHUTDOWN operating mode, overload is permitted for a defined time. The output is electronically shut down after the limit value has been exceeded (see Overload shutdown and carrying out a reset (Page 58)).

● In the CONSTANT CURRENT operating mode, an overload current is continually permissible (U/I curve) according to a defined characteristic. The overload current is limited to a maximum of 150 % of the setting value of the current potentiometer for a duration of 5 seconds (LED "ON/OFF/RST" of output 1 quickly flashes green); the current is then limited to 100 % of the setting value (LED "ON/OFF/RST" of the output slowly flashes green) as long as there is an overload condition.

In addition, in this operating mode, if a CNX8600 expansion module is not being used, a brief Power Boost (300 % for 25 ms) is provided so that the downstream circuit breaker can trip when an overload condition occurs.

3.7 Setting the on delay

In order to reduce the load on the overall SITOP PSU8600 power supply system as a result of simultaneous switch-on current peaks of the loads at the output of the basic device and at the outputs of the expansion modules, a switch on delay between the outputs can be selected when switching on.

When the on delay is activated, the outputs are sequentially switched-on with a 25 ms or 100 ms delay time between the outputs, or "load optimized". For a load-optimized on delay, after 100 ms, for the previous output n it is additionally checked as to whether the output current lies below the selected response threshold value. Output n+1 is switched-on as soon as this is the case. Outputs that have been shut down are not taken into account and are skipped.

3.8 Setting the output characteristic

For the standard output characteristic of the basic SITOP PSU8600 device, the output voltage is regulated to obtain a constant value independent of the output current. If the "soft" output characteristic is selected, then the output voltage slightly decreases as the output current increases. This output response can be used so that when two basic devices are connected in parallel to increase the power rating, the basic devices are more uniformly utilized.

3.10 Monitoring functions

SITOP PSU8600 basic units and SITOP CNX8600 expansion modules have integrated overtemperature monitoring functions. The outputs are shut down if the internal temperature is inadmissibly high.

Take the following steps after a shutdown as a result of an inadmissibly high internal temperature:

1. Check the mounting clearances of the devices, see Standard mounting position (Page 99) and Other mounting positions (Page 101). Excessively low mounting clearances cause overheating.

2. Measure whether the ambient temperature is permissible, see Environmental conditions (Page 303).

If an inadmissibly high temperature is detected inside the basic device, the output of the basic device and the expansion modules being used are switched off.

A shutdown as a result of an inadmissibly high temperature inside the basic units is signaled by:

● Red LED "OK"

① at the basic unit and at the supplementary modules

● LEDs "ON/OFF/RST"

● Signaling contact at the basic unit

If an inadmissibly high temperature is detected at an output, then the outputs at the expansion modules are shut down in pairs (1 and 2 or 3 and 4). The remaining outputs remain switched on.

System overload monitoring

Note

A shutdown as a result of a system overload can only occur when using expansion modules. When operating the basic device without expansion modules, the dynamic overload capability of the system cannot be exceeded as a result of the coordinated shutdown cha

When expanding the system using expansion modules (additional outputs), ensure that the sum of the set response threshold values of the output currents does not exceed the total power rating (current rating) of the system. Alternatively, by suitably configuring the load duty cycle of the individual outputs, you can prevent the total power from being exceeded.

Identifying a shutdown due to system overload

In order to permit brief, higher switch-on currents of the loads to be supplied, the system has a dynamic overload capability of 150 % of the rated power for a permissible duration of 5 s/min.

3.11 Activating and deactivating buffer operation

Using control contact ON (terminals "X1" and "X2") at SITOP BUF8600 buffer modules with double-layer capacitors, buffer operation can be activated, deactivated or exited when the power fails. Preventing or exiting buffer operation is especially interesting for non-operational periods, to prevent buffer components from being unnecessarily discharged. This then facilitates the fastest possible buffer readiness after switching on again.

Buffer operation is only possible if terminals "X1" and "X2" are connected at the buffer module. When delivered, this is implemented using a wire jumper. As a consequence, buffer operation can be enabled, prevented or exited using a floating contact (e.g. a contact in the plant or system). Instead of the wire jumper, the contact is closed, and this must have < 10 Ohm in the closed state. The buffer components are charged irrespective of whether contacts "X1" and "X2" are connected - or not.

1. Close the connection between terminals "X1" and "X2".

When the power fails, the power supply system is automatically buffered using the buffer components.

1. Open the connection between terminals "X1" and "X2".

When the power fails, the power supply system is not buffered using the buffer components.

Buffer operation is immediately exited if the connection between terminals "X1" and "X2" is opened during buffer operation.

4.6 System response for a modified hardware configuration

The system response of the SITOP PSU8600 after modifying the system configuration is explained in this section.

Modifying the system configuration involves changing, adding or removing individual components.

Before starting to make changes of any kind to the system configuration, the main switch of the system must be opened and measures taken to prevent it from being reclosed. If this instruction is not observed, touching live parts can result in death or serious injury.

SITOP PSU8600 does not check that the wiring is correct.

After making any changes to the system configuration, ensure that the wiring is correct in order to avoid damage to the system.

When the system starts or a configuration is loaded, the system compares the saved system data with the actual system configuration:

● Article numbers of the individual components installed

● Serial numbers of the installed individual components

● Positions of the individual components in the system configuration

● Firmware versions of the installed individual components

In the MANUAL operating mode, when the system starts, SITOP PSU8600 compares the existing system configuration with the system configuration that existed at the last complete system start.

For an unchanged system configuration, all outputs are activated with the last operating status before the shutdown.

In the REMOTE operating mode, when the system starts, SITOP PSU8600 compares the existing system configuration with the last hardware configuration loaded from a control system in the REMOTE operating mode.

For an unchanged system configuration, all outputs are activated with the parameters and operating states saved in the configuration. If, before the shutdown, the last operating state of an output was "Manually switched off (LED is lit yellow), "Automatically switch off due to

Standard mounting position

Output current as a function of the ambient temperature

The device is mounted on standard mounting rails according to EN 60715. The power supply system must be mounted in such a way that the input terminals and the output terminals are at the bottom to ensure correct cooling.

A clearance of at least 50 mm should be maintained above and below the power supply system (maximum depth of the cable duct, 50 mm).

No clearance is required at the side.
