CONTROLLER
e MCS-1-LCD multifunctional logic controller has integrated analogue, digital
and relay outputs which are free configurable. Its multiple analogue, digital and
temperature inputs ensure functionality in a large range of HVAC applications. All
functional parameters and settings are accessible either via a 4-button interface
with LCD display, via a user-friendly monitoring software application for Windows or

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.

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.

6. Check if your unit starts or terminates the network (see Example 1 and
Example2). 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.
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
MIW- MC S -1-LCD- E N - 00 0 - 20 / 07 / 2016 10 - 33
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.
