Notwithstanding the highest practicable protection means used in designing M.S. electronic circuits, the

electronic components and semiconductor devices mounted on the modules can be seriously damaged

by electrostatic voltage discharge which can be experienced when handling the modules. The damage

caused by electrostatic discharge may not be immediately apparent but the design reliability and the

long life of the product will have been reduced. The electronic circuits produced by M.S. are completely

safe from electrostatic discharge (8 KV IEC 255.22.2) when housed in their case; withdrawing the

modules without proper cautions expose them to the risk of damage.

Before removing a module, ensure that you are at the same electrostatic potential as the

equipment by touching the case.

Handle the module by its front-plate, frame, or edges of the printed circuit board. Avoid touching

the electronic components, printed circuit tracks or connectors.

Do not pass the module to any person without first ensuring that you are both at the same

electrostatic potential. Shaking hands achieves equipotential.

Place the module on an antistatic surface, or on a conducting surface which is at the same

potential as yourself.

Store or transport the module in a conductive bag.

More information on safe working procedures for all electronic equipment can be found in BS5783 and

IEC 147-OF.

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:

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.

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.

2.5 - Last events’ recording – time stamping.

The last 50 events (opening/closing of any input/output) are time stamped with a 10ms resolution and

stored into a non-volatile (E2PROM) memory.

All the recorded events are available via the serial communication interface with MSCom program.

2.6 - Logic matrix.

The output contacts are operated according to a programmable AND/OR matrix (see Figure 1) by the

following inputs:

Digital inputs I1..I14.

Front panel push buttons (On and Off).

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:

By examining such table, we can say that O1 is TRUE when :

I1 is TRUE AND I2 is NOT TRUE. (1)

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:

Write down the truth table relevant to the function which has to be implemented.

Express the function as sum of logic products.

Assign to each logic product a AND row.

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:

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.

(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.

(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:

2.8 - Configuration of outputs.

All the output contacts can be configured as:

Normally Energised or Normally De-Energised.

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.
