Check that the connections are tight.

 

Screw the cable glands tight by hand.

 Connection for 4-wire technique

 Connection for 2-wire technique

10.2     Connection of optional interfaces

• 

The following are options that the calculator can be equip-

ped with at the factory (state when ordering) and will vary 

depending on the individual calculator.

• 

Feed the cable to be connected (cable diameter Ø 3.5 to 6.5 

mm) through an opening on the bottom edge of the calcula-

tor housing into the space containing the terminal strips. 

• 

The terminal clamps are designed to 

fi

 t strands with ends 

with a cross-section of 0.5 – 1.5 mm

2

.  

• 

Clamp on the cable according to the following illustrations 

that apply depending on the interface.

Depending on the option, 

here there are located two 

additional pulse inputs (IN) 

for further meters or two 

pulse outputs (OUT) for 

connection to an additional 

system.
For connection of meters 

with open collectors atten-

tion must be paid to the 

polarity.

Polarity is not important for 

these connections so the wires 

can be clamped arbitrarily.
When the M-bus network is in 

operation a triangle will appear 

in the lower right corner of the 

display.  
(Power supply from the M-bus 

network is functioning.) 

Connection of M-bus

Connection of pulse outputs or inputs

Connection of power pack

It is strongly recom-

mended to use only the 

Engelmann Sensor 

power pack.
It is imperative to pay 

attention to the polarity

Important note:  The fl ow sensor is not powered by the 
                            power pack!

Attention: Please check the unused cable glands to make
                  sure that the necessary blind plugs are inserted
                  and then tighten the cable glands by hand. 

• 

Check that the connections are tight.

• 

The power pack should only be connected to 230V and 

checked by authorized technical personnel. 

• 

Check on the display whether a 

triangle appears in the lower right 

corner, as shown in the illustration.

• 

Screw the cable gland tight by hand.

• 

Close the cover of the calculator housing and protect 

against unauthorized opening using the delivered 

Optional

:

For the dual-purpose heat/

cooling meter version, sepa-

rate pulse outputs for heating 

energy and cooling energy 

are available.
