MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting your controller read carefully “Safety and
Precautions”. Choose a smooth surface for an installation location (a wall,
panel and etc.). Then proceed with the following mounting steps:
1. Switch off the power supply.
2. Unscrew the four screws on the front cover and open it carefully.
ATTENTION Make sure the flat cable, connecting the motherboard with the LCD printed circuit
board remains in place!
3. Insert the connecting cables through the cable glands of the unit.
4. Do the wiring according to the wiring diagram (see Fig. 1) using the information
from section “Wiring and connections”. Connect the controlled equipment and
the sensors (if necessary). Use cables with recommended length and type with
respect to your application. Mind the following recommendations:
►Use shielded cables for the analogue inputs / outputs in case the cable length
is between 4 and 12 m and voltage (VDC) mode is used.
►When the cable length exceeds 12 m, use the analogue inputs / outputs in
current (mA) mode.

ATTENTION When you first use the unit make sure that the load corresponds to the default
output values. If the default values do not fit the load used, configure the unit
first, then connect the load. Improper load may cause damage to the controller.

ATTENTION Do not mix the temperature ground (GND) with other ground (GND) terminals!
5. Customise the factory settings for the PWM outputs to the desired ones if you
are going to use a PWM output. By default the IPWM1 and IPWM2 jumpers (Fig.
2) are closed and the PWM outputs 1 and 2 are connected to an internal voltage
source of +12 VDC. See Fig. 3a Internally supplied PWM schematic. Remove
the jumpers (Fig. 2) if you need PWM open collector outputs. See Fig. 3b Open
collector schematics.

Example2). If it does, connect the NBT resistor. Place the NBT jumper (Fig.4)
onto the pins. Otherwise leave it disconnected (default setting).

8. Close the enclosure and fix the cover.
9. Switch on the power supply.
ATTENTION If an AC power supply is used with any of the units in a Modbus network the
GND terminal should NOT BE CONNECTED to other units on the network or
via the CNVT‑USB‑RS485 converter. is may cause permanent damage to the
communication semiconductors and / or the computer!
10. If necessary, customize the other factory settings to the desired ones. Use
3SModbus software, 3SMonitor software or the 4-button menu and LCD display
VERIFICATION OF THE CORRECT INSTALLATION
When you first switch on the power supply, the display will illuminate and show the
time and date, Temp. °C (the default operational mode) and the active working mode
(Run or Stand-by). If this is not the case, open the enclosure and check the status of
the power on green LED. See Fig. 7 Operating indication.
■If the LED is off, your unit is not supplied. Check the connections again.
■If the LED is on, but the LCD display is off, check the connection of the ribbon
(flat)cable.
Fig. 7 Operation indication
ATTENTION Be careful when you are handling with the ribbon cable. It must not touch the
power supply block. is will damage your unit. See Fig. 8.

CONTROL FUNCTIONS OVERVIEW
e MCS-1-LCD controller features integrated analogue and relay outputs which can
be controlled either in one of the pre-configured modes or they can be personalised.
Its numerous different analogue, digital and temperature inputs ensure a large range
of functional control. You can choose the control function between:
LINEAR FUNCTION
Analogue outputs in linear function of the inputs
In cool mode the value of the analogue output rises linear in function of a higher
measured input value (according to the sensor(s) selected). is linear function goes
from the minimum to the maximum range of the assigned input and drops to 0 VDC
when off level is reached. e off level can be selected over the full sensor range.
In heat mode the value of the analogue output drops linear in function of a higher
measured input value.

CONTROLLER

www.sentera.eu
MIW-MCS-1-LCD-EN-000-20/07/2016 13 - 33
back to the table of contents
CONTROL FUNCTION
Analogue outputs in function of the normal priority and high priority inputs
e value of an analogue output in control mode follows a linear function of the
input with normal priority until the high priority assigned input reaches its setpoint.
e value then rises to the maximum value in the selected “time to maximum”
timespan. e output stays at maximum until the high priority input value reaches
SP – hysteresis, and then it drops following the linear function of the input with
normal priority.
PID CONTROL
During the PID control the analogue output changes to keep the assigned normal
input value at its selected setpoint level. e proportional gain (Kp), integration
period (Ti) and derivation period (Td) of the PID control are free configurable to set
the required slope, gain or magnitude.
e implemented autotune function calculates the parameters automatically
according to the system.
ANALOGUE OUTPUTS IN FUNCTION OF THE DIGITAL INPUTS
e analogue outputs can individually correspond to the state of the digital input.
When a digital input with remote off function becomes ‘active’, the related analogue
output drops to 0 and goes back to the current function value (Linear, Control or PID)
when it becomes ‘inactive’. When a digital input with ‘maximum output’ function
becomes ‘active’, the related analogue output rises to maximum and goes back to
the current function value (Linear, Control or PID) when it becomes ‘inactive’. All the
digital inputs have priority to all the other inputs (Ai1, Ai2, T1 and T2).
FREE
e second analogue output Ao2 is independent from the first analogue output Ao1.
BALANCED
e value of the second analogue output Ao2 follows the value of the first output Ao1.
UNBALANCED
In unbalanced mode the value of the second analogue output Ao2 follows the function
of the first output Ao1 according to the set offset values. See the operational
diagrams with positive and negative unbalanced (offset) coefficient.
RELAY CONTACT FUNCTION
Depending on the pre-selected active state of a relay, the relay contact switches
open or closed at the previously set setpoint of the assigned analogue or temperature
input, and switches back (closed or open) at the SP - hysteresis value.
In case there is an assigned digital input for relay switching, the relay contact
switches open or closed at the event of active state and switches back (closed or
open) when the state changes to inactive.
