5. Стр. 7 3.4 Power decrease for increased ambient temperatures

   The unit´s maximum permissible ambient temperature is depending on version 40° C, or 50°C.Up to that temperature a load of the quoted rated current is possible. The removal of heat in the unit due to power dissipation is dependent on the ambient temperature, so the maximum load has to be reduced if…

Use the appropriate mounting devices for proper installation of the unit! • Do not mount equipment on vibrating base! • Use the appropriate fixing equipment. The plastic washers must be installed between…

7. Стр. 9 5. Electrical connections

   5.1 Mains connection Power from the mains is connected to terminals: PE, L1, L2, L3, and N. Here, it must be strictly observed that the mains voltage lies within the allowable tolerance specifications () General description: Technical data and nameplate affixed to the side). The neutral conductor…

8. Стр. 10 5.4 Motor noise

   Motor noise can occur when fans are controlled using electronic voltage controllers (Phase cutting = series “P...”). Such noise can be system-dependently perceived as a disturbance. This noise is relatively low for fast-running fans where the noise from the air is high. The noise from motors in…

9. Стр. 11 5.8 Enable ON / OFF

   Enable ON / OFF (electronic disconnection) and reset after motor fault via potential free contact, terminals „D1“-„D1“. ♦ Device ON with contact closed ♦ Device OFF with contact open (“Fault“ relay K1 not released, terminals 11-14 bridged) Display for disconnection: Green LED flashes No…

10. Стр. 12

    The signal from the sensor for detection of the actual value is connected to the terminals “E” or “E1”and “GND”, for sensor in two-wire-technology (output 4-20 mA) to terminals "E" (E1) and "24 V". Be sure to observe correct polarity. The maximum length of the connecting cable shall be 30 m…

11. Стр. 13 6. General settings and operating elements

    6.1 Programming the operating mode (speed controller / P- controller) It is possible to use the device as a speed controller or as a P-controller. Selection of the function must first be made by setting the internal dipswitch and Jumper. Caution: not under voltage! Observe the safety notices!…

12. Стр. 14 6.2 Controls

    Operation as a speed rcontroller For operation as a speed controller, the output voltage is set manually by adjusting the built-in potentiometer, by an external potentiometer or external signal (0-10 V). Setting Potentiometer Output voltage 0-100 % (switch S1-3 ON position) (Control by internal…

13. Стр. 15 7. Settings for operation

    7.1 Settings for operation as a speed controller U Motor 100 % n-min = 0 % n-max = 100 n-max n-min = 35 % n-max = 85 % The output voltage is switched off to “0” for a controller signal less than 15 % of approximately 15 % of the mains voltage that is applied. For a controller signal greater than 20…

14. Стр. 16 7.1.5 Operation with two variable output voltages (2 steps)

    Switchover between two variable output voltages for the operational mode of external control (Dipswitch S1-3 OFF position) is possible by means of external potential-free contact-making. "E" "A" (+10 V) Step 1 (low speed) When there is no input signal connected to the input terminal “E“ or “E1”…

15. Стр. 17 7.2 Settings for operation as a controller

    U Motor 100 % n-min = 0 % n-max = 100 % n-max n-min = 35 % n-max = 85 % The output voltage is switched off to “0” for a controller signal less than 15 % of approximately 15 % of the mains voltage that is applied. For a controller signal greater than 20 %, the output voltage is switched on to approx.…

16. Стр. 18 7.2.2 Adjusting the control range via potentiometer “Pband”

    The control response can be adjusted to the system conditions with this setting - small control range = greater amplification and shorter control times - big control range = longer control times and higher controller stability Pband 5 30 % ♦ At active sensors with 0-10 V or 4-20 mA (factory setting)…
