Before working on the Type 2510 Diagnosis device socket,
always switch it free of voltage. Exception: Setting the
potentiometer.
INSTALLATION / PUTTING INTO SERVICE
• Clamp the lines as shown in the connection diagram (Figure 3)
• Switch on the electrical power supply
• Plug in the device socket
SETTINGS (See Figures 3, 3.1, 3.2, 3.3)
NOTE: The solenoid valve must be closed while setting up (no flow)
1. Turn the potentiometer to the left (Fig. 3.1) => LED lights up
2. Turn the potentiometer slowly to the right until the LED goes out (Fig.
3.2)
3. Turn the potentiometer further to the right by one graduation (Fig.
3.3). NOTE: There must be a "Low signal" at the binary output!
4. Open the solenoid valve (Flow) => LED must light up!
NOTE: There must be a "High signal" at the binary output!
ATTENTION! Check these settings regularly every three months
depending on the variations of the medium temperature.
An increase of the medium temperature > 24°C/min can lead to
incorrect messages!
• Secure the device socket using the cheese-head screw
(max. tightening torque 1 Nm).
ATTENTION! When screwing the device socket onto the solenoid
valve, ensure that the seal is properly seated!
Applications affecting Safety
Before using the Type 2510 Diagnosis device socket in systems which
affect safety, please consult your local Bürkert branch!
