Figure 4-3: Limit switch settings Adjusting the limit switch with reed contact: • Slacken nut 3 • Set reed cartridge to the required value • Secure with nut 3 Comment The reed contact is actuated directly by the float magnet. The desired operating point can only be determined in measuring mode. A reference to the scale and/or pointer cannot be established. 16 www.krohne.com 01/2012 - 4000287103 MA DK32-34-37-R05-en
