0 ... 10 V signal
• Electric strength 30 V DC/24 V AC
• Input resistance of the voltage input > 10 kΩ
7.2.4 SSM signal properties
An integrated collective fault signal is applied as a potential-free normally closed contact.
Contact load:
• Permitted minimum: 12 V AC/DC, 10 mA
• Permitted maximum: 250 V AC, 1 A, (AC1 power factor > 0.95). 30 V DC, 1 A
DANGER
Risk of fatal electrical shock!
Improper connection of the collective fault signal (SSM) contact poses a risk of fatal injury
due to electric shock!
7.2.5 Signal cable
• The bare cable end is to be inserted in the system's switchbox. Observe cable assignment!
• Ensure that the connecting cable does not contact either the pipes or the pump.
Cable assignment
2-wire cable
4-wire cable
The design of the control cable should contain the features of the following table:
