Contact open Automatic OFF, signal by symbol on the dis-
play
6.2.8 Protection against low water level
CAUTION
Property damage due to external voltage!
External voltage at the signal terminals will damage the product.
• Do not connect any external voltage to the terminals.
• The protection against low water level can be connected via a potential-free contact
(normally closed contact).
• Connect the corresponding terminals according to the circuit diagram.
• Remove the factory pre-assembled converter bridge.
Contact closed no low water
Contact open Low water
6.2.9 Collective run/collective fault sig-
nals
DANGER
Danger of death due to electrical current!
The external electrical power supply is also present at the terminals when
the main switch is switched off!
• Disconnect the external power supply before any work.
• Potential-free contacts (changeover contacts) for external collective run and collective
fault signals (SBM/SSM) can be activated.
• Connect the corresponding terminals according to the circuit diagram.
• Min. contact load: 12V, 10mA
• Max. contact load: 250 V, 1 A
6.2.10 Display target pressure
CAUTION
Property damage due to external voltage!
External voltage at the signal terminals will damage the product.
• Do not connect any external voltage to the terminals.
A 0...10V signal is available for an external measurement / display option of the current
controlled variable actual value.
0V corresponds to the pressure sensor signal 0 and 10V corresponds to the pressure
sensor limit value.
• Connect the corresponding terminals according to the circuit diagram.
Sensor Display pressure range Voltage/pressure
16bar 0 ... 16bar 1V = 1.6bar
6.2.11 ModBus TCP connection
CAUTION
Property damage due to external voltage!
External voltage at the signal terminals will damage the product.
• Do not connect any external voltage to the terminals.
The ModBus TCP protocol is available for connection to a building management system. In-
sert the connection cables laid by the customer through the threaded cable glands and se-
cure. Connect via LAN1 bush on the printed circuit board.
Observe the following points:
• Interface: Ethernet RJ45 plug
