2 - GENERAL CHARACTERISTICS AND OPERATION
2.1 - Digital inputs
14 optoisolated self-powered inputs controlled via cold contacts with antirebound logic:
No-Load output voltage
:
Vout = 30Vcc
Minimum pick-up current
:
Iout = 5mA
Max load resistance
:
4000 
Each input is sampled every 1ms. An input is considered to be in the 1 logic state when its terminals
are shorted (<4000 ).
The logic state of an input is valid if it doesn’t change for at least 5ms. As a consequence any input
pulse shorter than 5ms is ignored by the unit.
2.2 - Output contacts
Five output relays are available : R1, R2, R3, R4, R5 with one N/O contact (NC on request):
Rated current and voltage
:
5A - 380V
AC resistive switching
:
1100W max 380V
Make
:
30A (peak) 0,5 sec.
Break
:
0,5A 125VDC, L/R = 40ms, 10 ops.
2.3 - Power supply
Power supply input (terminals 12-13) is multi-voltage autoranging 2kV isolated, has no
polarity and can accept any AC or DC voltage in the range a or b
- Consumption 5W \ 12VA (all outputs energized).

2.4 - Serial Communication
Two ports are available for serial communication:
o
A RS232 serial communication port, MODBUS RTU protocol at 9600bps, is located on relay’s
front (9 pins SUB-D connector). This port is active only when a dedicated cable (see § 6) is
physically connected to it, thus allowing the user both to configure/test the unit and to
completely monitor its status by means of a P.C.
o
A second RS485 serial communication port, MODBUS RTU protocol at 9600bps, (terminal
blocks 1..2) allows the MX14-5 to be connected to a central supervision system. This port is
active only when the front panel port is not in use (cable physically disconnected) and makes
the internal data base available to the central supervision system.
A communication software (MSCom) for Windows 95/98 is available, covering both the configuration
and the monitoring tasks. Please refer to the MSCom instruction manual for more information.

2.6 - Logic matrix.
The output contacts are operated according to a programmable AND/OR matrix (see Figure 1) by the
following inputs:
o
Digital inputs I1..I14.
o
Front panel push buttons (On and Off).
o
Internal fault diagnostic signal (I.R.F.)
Note that in remote operation mode, the front panel push buttons are ignored and they can be operated
only via the serial communication interface. In the remote mode it is also possible for the user to
change from 0 to 1 the status of the digital inputs via the serial port.

The state of each AND row is calculated as the logic product of the inputs which are on the same row,
while the state of each OR column is obtained as the logic sum of the selected AND rows.
The outputs are controlled by the relevant columns with a user programmable delay.
Figure 1 shows a simple programming example.
The following logic function of I1 and I2 is implemented:
O1 = I1 I2. (XOR exclusive OR) 
I2xI1I2xI1 
If we write down the truth table relevant to the XOR function we have:
I1
I2
O1
0
0
0
1
0
1
0
1
1
1
1
0
By examining such table, we can say that O1 is TRUE when :
I1 is TRUE AND I2 is NOT TRUE. (1)
OR
I1 is NOT TRUE AND I2 is TRUE. (2)
If we now want to program the MX14-5 to implement the XOR function, we just reserve two AND rows
for statements (1) and (2) and then connect those rows to the OR column corresponding to output O1.
Generally speaking, a method for programming the internal logic matrix consists of the following steps:
o
Write down the truth table relevant to the function which has to be implemented.
o
Express the function as sum of logic products.
o
Assign to each logic product a AND row.
o
Connect the resulting AND rows to the OR column corresponding to the output which has to
be activated.
The application program MSCom provides a programming windows same as Fig.1

2.7 –Operating modes
Three main operating modes are available:
o
Lock/PRG
(Lockout mode
factory default)
:
This mode allows the user to change the settings and to run the automatic
self-test procedure. When this mode is entered the output relays are blocked
and the inputs are disregarded.
o
L
(Local mode)
:
In this mode the inputs can only be controlled via the relevant terminals of the
MX14-5. In the local mode N° change of configuration or test command via
push buttons or serial port is accepted.
o
R
(Remote mode)
:
In this mode all the inputs are sill controlled via the relevant terminals but their
status can also be changed from 0 to 1 (not from 1 to 0) via the serial
communication interface. The push buttons on relay front face are
disactivated: their function is controlled via the serial interface.
N° change of configuration is accepted.
The following table summarizes the three operating modes:
Local mode

All the output contacts can be configured as:
o
Normally Energised or Normally De-Energised.
o
Instantaneous or delayed (0.01 to 655s). Different values can be selected for set and reset
time delays of any relay.
The time needed for the acquisition of the status of the inputs (50ms) must be added to the
set operation time delay.

2.10 - Real time clock.
The unit features a built in clock calendar with Years, Months, Days, Hours, Minutes, Seconds, Tenths
of seconds and Hundredths of seconds.
2.10.1 - Clock synchronization.
The clock can be synchronized via the serial communication interface.
The following synchronization periods can be set: 5, 10, 15, 30, 60 minutes.
Synchronization can also be disabled, in which case any synchronization command is ignored.
In case synchronization is enabled, the unit expects to receive a sync signal at the beginning of every
hour and once every Tsyn minutes. When a sync signal is received, the clock is automatically set to the
nearest expected synchronization time.
For example: if Tsyn is 10min and a sync signal is received at 20:03:10 of January 10th, 98, then the
clock is set to 20:00:00 January 10th, 1998.
On the other hand, if the same sync signal was received at 20:06:34, the clock would be set to
20:10:00, January 10th 98.
Note that if a sync signal is received exactly in the middle of a Tsyn period, the clock is set to the
previous expected synchronization time.
Warning: if time is adjusted (via the serial port) while synchronization is enabled, the clock stops and
can be restarted only by sending a sync. message.
2.10.2 - Resolution.
The clock has a 10ms internal resolution.
2.10.3 - Operation during power off.
The unit features an on board Real Time Clock which maintains time information for at least 1 hour in
case of power supply failure.
2.10.4 - Time tolerance.
During power on, time tolerance depends on the on board crystal
(+/-50ppm typ, +/-100ppm max. over full temperature range).
During power off, time tolerance depends on the RTC’s oscillator
(+/-50ppm typ, +65 –270 ppm max over full temperature range).
2.11 - Diagnostics
The unit features three different self-test procedures:
o
Start-up test: this is activated at power-up. The on-board E2PROM and RTC are tested. The
software also looks for stuck keys on the front panel.
o
Periodic test: this is activated every 10mins and checks the contents of the on board E2PROM.
o
User-requested test: this is activated whenever a test command is issued to the unit while
working in lock-out mode (via front panel or serial communication interface).
The E2PROM is tested and all the leds are lit-on for 4 seconds.
In case errors are detected the lock-out mode is automatically entered and the Ax/I.R.F. green led
starts flashing.

3.2 –Input and Output Configuration
At the end of the matrix programming, activate function “Settings”. Herebelow window will be displayed.
3.2.1 –Output relay configuration
o
Output relays can be programmed to be normally energized or normally deenergized, activating
or not activating the correspondent box.
o
In the normally energized configuration, the output relay is energized when the correspondent
command is set “ 0 ” while it is deenergized when the command is set to “ 1 “.
o
In the normally deenergized configuration, the output relay is deenergized when the
correspondent command is set to “ 0 “ while it is energized when the command is set to “ 1 “.
3.2.2 –Delay of output relay operation
For each relay (R1, R2, R3, R4, R5) it is possible to program the Response Time delay (TO1, TO2,
TO3, TO4, TO5) to the state “ 1 “ of its operation logic.
3.2.3 –Delay of output relay reset
For each relay (R1, R2, R3, R4, R5) it is possible to program the Response Time delay (TR1, TR2,
TR3, TR4, TR5) to the state “ 0 “ of its operation logic.
3.2.4 –Output relay operation delay
For each relay (R1, R2, R3, R4, R5) set the operation time delay in seconds (TO1....TO5).
3.2.5 –Output relay reset delay
For each relay (R1, R2, R3, R4, R5) set the drop-off time delay in seconds (TR1....TR5)

3.3 –Selection of remotely controlled inputs
Select the inputs to be remotely controlled by activating the correspondent box.
3.4 –Activation of the remotely controlled inputs
The inputs selected for remote control can be forced from status “ 0 “ to status “ 1 “ activating the
correspondent box. Activation via the serial port is possible only if the relay is in REMOTE mode.
N.B. Inputs already in the status “ 1 “ cannot be switched to the status “ 0 “ via the remote serial
command.
3.5 –Selection of the Node address
The node address is the call number to which the relay will answer during operation on serial line.
Always choose a number different from those used for other relays connected to the same line. Set the
node address and press the button “SEND” to confirm the number. The relay accepts its address
number and the communication is interrupted. To start again the communication, go back to the
window “Relay Manager” and ask again the connection of the relay using its number.
4. Monitoring INPUTS/OUTPUTS Status
It’s possible to monitor the status of inputs, commands and outputs through serial communication.
For this reason, after connection to MSCom, select the windows “Status”.

7. MAINTENANCE
No maintenance is required. Periodically a functional check-out can be made by operating the TEST
button on relay’s front. In case of malfunctioning please contact Microelettrica Scientifica Service or the
local Authorised Dealer mentioning the relay's Serial No reported in the label on relays enclosure.
IMPORTANT NOTICE: in case of E2PROM error (green led Ax/I.R.F. flashing after power-up
or a test) try the following recover procedure:
Run a user-requested test.
If the error is reset (green led Ax/I.R.F. lit) turn the relay off and then on again. Check relay’s settings via
the serial communication interface before restarting normal operation.
If the error is not reset repeat the operations listed at point 1.
If the error can’t be corrected please contact Microelettrica Scientifica Service or the local Authorised
Dealer
8. POWER FREQUENCY INSULATION TEST
Every relay individually undergoes a factory insulation test according to IEC255-5 standard at 2 kV, 50
Hz 1min.
Insulation test should not be repeated as it unusefully stresses the dielectrics.
When doing the insulation test, the terminals relevant to serial output must always be short circuited to
ground. When relays are mounted in switchboards or relay boards that have to undergo the insulation
tests, the relay modules must be drawn-out of their enclosures and the test must only include the fixed
part of the relay with its terminals and the relevant connections.
This is extremely important as discharges eventually tacking place in other parts or components of the
board can severely damage the relays or cause damages, not immediately evident to the electronic
components.
