<strong>DK32</strong> - DK34 - DK37<br />
Connection three-wire reed contact<br />
Figure 4-2: Electrical connection of reed contact limit switch<br />
Str<strong>and</strong> colours for flowmeters with preassembled cables:<br />
1 Silicone-insulated wire - yellow/green / FEP-insulated wire - red<br />
2 Silicone-insulated wire - brown / FEP-insulated wire - brown<br />
3 Silicone-insulated wire - blue / FEP-insulated wire - blue<br />
4.3 Setting the limit switch<br />
Set the pointers to the desired limit values as a min. contact 1 <strong>and</strong> max. contact 2 using a slip<br />
coupling along the scale.<br />
Figure 4-3: Limit switch settings<br />
Adjusting the limit switch with reed contact:<br />
• Slacken nut 3<br />
• Set reed cartridge to the required value<br />
• Secure with nut 3<br />
Comment<br />
The reed contact is actuated directly by the float magnet. The desired operating point can only be<br />
determined in measuring mode. A reference to the scale <strong>and</strong>/or pointer cannot be established.<br />
