Display, buttons and parameters

The default/delivery setup is 0000. In this configuration the password input is not 

activated. To activate the password protection (menu 12) change the 4 digits into your 

choosen numbers (e.g. 1234) and press ENTER. 

Please keep your password in mind for next parameter change! Due to a new parameter 

setup the password is requested.

Change operation – parametrisation mode

To change from operation to parametrisation mode and vice versa, push         ENTER 

button for minimum of 3 seconds. Back over the menu “Save” and exit. 
Display in operating mode

In operating mode the current set value, the actual value and the set value are dis-

played. The red and the green LED indicate the current operating status. 

When the green LED is illuminated continuously, the system is in a stable state and 

indicates correct operation. If the limits of the actuator’s position are reached or an 

internal fault is detected, the red LED lights up. 

A flashing red LED indicates that the set point can not be achieved. The alarm func-

tion is active in this case. The yellow LEDs indicate during adjusting phase the direc-

tion of movement of the actuator. The upper LED denotes the actuator opens, the 

lower LED indicates the actuator closes. The yellow LED does not flash when the 

system is within the defined tolerance field (menu 12 “Controller / tolerance”). 

Zero point compensation

...Reg-V-... controller are equipped with a zero point compensation to adjust the module to 

the installation position. The pressure nipples P+ / P− must be connected with a short circuit 

tube and the zero point compensation performed by following the menu for parametrization 

(menu 3.2). 

Before starting the zero point compensation, the device should be connected to power 

supply for a minimum of 15 minutes to reach the uniform working temperature!

Control speed

ExMax-...-CY...  –  see additional data sheet

...Reg-V300 and ...-V300-A are designed for the control of volume flows. The control mode 

can be set in menu 8 “Controller”. Normally, the fully automatic determination of the control 

parameters (select “Auto”) is sufficient. In addition, an adaptive PID (proportional component 

is calculated automatically) and a standard PID controller can be selected. These settings 

should only be used by trained personnel.

In certain cases – especially in severe pressure fluctuations in the air duct – the gain of the 

control loop (menu 8.2) and the control tolerance (menu 8.6) should be adjusted.

The control speed can be determined directly over the motor running time of the actuator. 

The control parameters in this case must not be changed. The controller recognizes the 

change automatically via the feedback signal of the actuator (terminal 7). This applies to 

all controller settings. The control speed depends only on the used motor running time. 

For more information see data sheet of the actuator. 

A.  Installation, commissioning, maintenance
All national and international standards, rules and regulations must be complied with. 

For electrical installations design, selection and erection, EN/IEC 60079-14 can be 

used.

Attention: Apply all Ex rules and regulation before opening the internal terminal 

box. Do not open cover when circuits are live! 

Draw the wiring cables through the cable glands. For connection use the internal Ex-e 

approved terminal box and connect equipotential bonding. 

After connection install the cables in a fixed position and protect them against mechanical 

and thermical damage. Close all openings and ensure IP protection (min. IP66). 

Avoid temperature transfer and ensure not to exceed max. ambient temperature! For 

outdoor installation a protective shield against sun, rain and snow should be applied.

After mounting and installation a zero point compensation must be done to ensure 

correct measurement results (see description). 

Sensors are maintenance free. An annual inspection is recommended. For electrical 

installations inspection and maintenance, EN/IEC 60079-17 can be used. 

Clean with damp cloth only.

Ex sensors must not be opened and repaired by the end user.
B.  Long cabling
We recommend using shielded signal wires and to connect one end of the shield to the 

...Reg-... terminal box.
C.  Separate ground wires
For supply and signal wires use separate grounds.
