Red led ST:
- is alight when the STOP (STP) input is closed
- is switched off when the STOP (STP) input is open.
Green led START:
- is alight when the OPEN/STEP/STEP (STR) input is closed.
- is switched off when the OPEN/STEP/STEP (STR) input is open.
7. PROGRAMMING THROUGH GTSYSTEM
The GTSYSTEM is an autonomous multi-functional terminal that can be used on various Prastel products both
for testing and function modification. In the case of UNIK2E control unit, it allows:
• modification or visualisation of operating parameters,
• visualisation of the counter of completed manoeuvres,
• visualisation of the control unit status and diagnostic messages.
8. ACCESSORIES ABSORPTION CHECK INFORMATION
(Transformer dimensioning)
The current available for the accessories is given by the power available for the accessories divided by the
voltage of the accessories (13.7V).
The power available for the accessories is given by the transformer power, less the motor power, less the power
absorbed by the control unit (4W).
Pacc = Ptras – Pmot – 4
Below are two examples of calculation of the current available for the accessories.

UNIK2E 100VA 85W 4W 11W 13.7V 800mA
The following table shows the average absorption of the most common Prastel/VDS accessories:
Product Absorption
Flashing Light FEBOLIX 150 mA
Photocell FOTO30SDE (couple TX+RX) 50 mA
Photocell FOTO35SDE (couple TX+RX) 50 mA
Induction detector MLX24AZ 40 mA
Receiver MR1E 20 mA
Microwave detector DM30 80 mA
Microwave detector DM60 100 mA
Amplifier for infra-red barrier FOTOTEST2D 30 mA
Pneumatic edge receiver TCO4RX 30 mA
Standalone keypad EASYBKA 100 mA
Standalone proximity reader EASYMINI 30 mA
Example: connecting 2 pairs of FOTO30SDE photocells, a FEBOLIX flashing light and a MLX24AZ detector the
overall average absorption is 290mA. Should it be necessary to connect accessories with an overall average
absorption that is more than that available, the transformer must be replaced with a more powerful one. For
12VDC motors use transformers with a secondary of 12VAC (for 24VDC motors use a transformer with a
secondary of 20VAC).
