IRMS. Please read the following instructions carefully, as this will allow you to use the intelligent system you have purchased to
its full potential.
Please keep this user manual in a safe place.
© All reproduction of this user manual, whether wholly or in part, is strictly prohibited, without the prior consent of
SCHRACK reserves the right to modify the product without prior notice.
2. GENERAL DESCRIPTION OF THE SYSTEM
The IRMS (Intelligent Redundant Multi Switch) unit has been designed to allow you to install and manage eight network
users from a single point, using one or two power supply lines, either direct from the mains power supply or served by an UPS.
2.1 LOAD DISTRIBUTION
The power supplies have been designed to guarantee operation of the system under extreme conditions:
•a single line supplying 180Vac (RMS);
•two lines simultaneously providing 265Vac (RMS).
In this way, the control system is guaranteed to function even with a reduction or strong disturbance in the power supply.
2.2 INTERVENTIONS
The IRMS automatically switches the power supply to an alternative source when the loads connected to a line undergo a
blackout. The duration of the voltage blackout required to switch the power supplies can be programmed using the system’s
software (SW).
In order to minimise the intervention time, switching does not just occur when the line voltage reaches zero, but is
instead immediate.
The system will disconnect a load when the current (RMS value) exceeds the maximum value for a single output
(3Arms).
The disconnection of a load occurs within 0.8÷1sec, on average, from the time the current value is exceeded.
The system is controlled by a microprocessor (μP), which carries out all the basic, real-time and communication
functions.
The external communication protocol ensures that all basic functions are activated and that all quantities are monitored.
The switching system is driven by a series of relays that have been designed and programmed in such a way as to
minimise the intervention times.
In order to ensure that the loads are not accidentally disconnected if a malfunction occurs to the microprocessor, a
“watch-dog” circuit automatically sets the IRMS to its default settings, i.e. with all eight users powered by the main power
supply line “A”.
Figure 1 is a block diagram of the IRMS.

Figure 1: Block diagram of the IRMS
So that it will operate when at least one of the two lines “A” or “B” is present, the power supply is redundant.
Relays RL1, RL2, RL3, RL4, RL5, RL6, RL7, RL8 switch the output loads from line A to line B, whilst relays RL9, RL10,
RL11, RL12, RL13, RL14, RL15, RL16 disconnect the loads.

3. INSTALLATION
Remove the machine from its packaging with caution.
Attach the handles to the side of the IRMS with the appropriate screws as depicted in the figure.
For greater safety and to avoid making the wrong connections, only use the cables that were supplied with the machine.
Figure 2 below shows the various possible power supply configurations of the IRMS.
Configuration (a) is the best in terms of:
•reliability;
•protection and continuity of the electrical power supply.
In configuration (c), lines “A” and “B” are either two separate lines, or are separated by two different disconnecting switches
above the IRMS system.
Figure 2: The different possible configurations of the IRMS
The IRMS measures the shift between the two power supply lines “A” and “B” and, whenever this shift exceeds 11 degrees,
displays an alarm message on the LCD display. In cases (a) and (b), it is important when installing the machine to ensure that the
two lines “A” and “B” are not in push-pull. Should this occur, the LCD display will indicate this, and the person installing the
system should rectify the problem by reversing the connections in the power supply plug of the UPS/one of the UPS.

4. SAFETY GUIDELINES
In order to ensure safe use of the equipment, a number of basic safety precautions need to be observed.
These may be summarised as follows:
•do not use the machine with wet hands;
•do not use the machine in bare feet;
•ensure that water or other liquids do not penetrate the machine;
•do not use the machine if the power supply cable is damaged;
•do not pull the power supply cable to disconnect the power supply;
•do not attempt to open the machine or to repair it;
•replace the fuses only with fuses of the same type;
•all maintenance operations must be carried out by qualified personnel;
•ensure that children, persons unauthorised etc. do not use the machine.
5. SIGNALS AND ALARMS
The IRMS LCD display provides the user/operator with all the information relating to the operating status of the machine and
warns of any conditions that warrant an alarm.
The display has two lines: a status line (top) and a status/alarm line (bottom).
The four possible operating conditions are shown in Figure 3.
Where there is no blackout but a shift of between 0° and 11° occurs, the two lines of the LCD display show the status of the
outputs, the line data (two at a time with the delivered power in VA), and the data of the loads (1, 2, 3, etc…) connected to the
line, as shown in Figure 3-a and 3-b.
When a blackout occurs on one of the two input lines, or where a shift of more than 11° occurs between the two lines, the
LCD display indicates this on the status/alarm line (Figure 3-c and Figure 3-d).
The shift reading is given in multiples of 111.
Figure 3: IRMS LCD display
The IRMS does not emit any acoustic alarm. Presence of an alarm is indicated solely on the LCD display.
1The sampling interval is 600 μs: the sine wave is subdivided into 32 parts; thus 360°/32 ≅11°.

6. INTERFACING
6.1 IRMS WITH SNMP NETWORK ADAPTER
The Network Card allows you to connect the IRMS directly to an Ethernet node; the machine is controlled directly using
the SNMP protocol.
The IRMS sends information concerning the status of the system via the network (SNMP TRAP).
LAN interface description (Front view)
1. RJ-45 socket for connection to a LAN (Ethernet);
2. Network Card unit RS232 serial socket to configure network parameters (IP address, SNMP communities, etc.);
3. The RESET button allows you to reset the Network Card module
The two LEDs display provides the user/operator with the signals regarding the operating status of the machine.
6.2 NETWORK CONFIGURATIONS

7. STRUCTURE OF THE IRMS
Figure 4 shows the front and rear views of the IRMS, whilst Figures 5 and 6 show the input socket with 10A delayed fuse
and the internal structure and wiring diagram of the IRMS respectively.
The IRMS has two male IEC power supply input sockets on the rear and eight female IEC output sockets on the front.
Figure 4: Front and rear view of the IRMS
NOTE: The IRMS does not have an ON/OFF button. Therefore, it is necessary to disconnect the power cables and the load
cables before accessing the internal components of this machine.
NOTE: The two IEC input line sockets carry a 10 A delayed fuse (figure 5). To replace the fuses, it is necessary to disconnect
both the power supply and load cables.
