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.

6. Check if your unit starts or terminates the network (see Example 1 and

Example2). If it does, connect the NBT resistor. Place the NBT jumper (Fig.4)

onto the pins. Otherwise leave it disconnected (default setting).

7. Fix the rear lid of the enclosure on the wall/panel by the delivered dowels and

screws. Mind the correct mounting position and unit mounting dimensions.

(SeeFig. 5 Mounting dimensions and Fig.6Mounting position.)

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.
