-
Does the directional arrow on the flow meter match the actual direction of flow?
-
Check that there are no leaks.
-
Is a flow volume displayed?
-
Are all shut-off valves open?
-
Is the heating (heating/cooling) system clear (dirt filters not clogged)?
-
Is a plausible temperature difference displayed?
When the components are functioning properly, attach the seals to the temperature sensors and the flow meter.
Protect the calculator against unauthorized opening using the numbered adhesive seal enclosed. The added bar
code label can be used for the purpose of documentation.

Interfaces and Options
7.1 Optical (infrared) interface
For communication with the optical interface an optocoupler and the “Device Monitor” software are necessary.
The optocoupler and “Device Monitor” are available as accessory equipment.
The optical infrared interface will be activated by automatically sending a header (according to EN 13757-3). Baud
rate: 2400 baud. Then you can communicate with the calculator for 4 seconds. After every valid communication the
calculator is open for another 4 seconds. Afterwards the display is deactivated.
The number of read-outs per day via the optical interface is limited. During daily read-out at least 4
communications are possible. If read-outs are carried out more rarely, the possible number of communications will
increase.
7.2 Retrofitting with an additional communication interface
To our calculator further communication interfaces can be added later. You will find the description of our optional
interfaces in the operating instructions „Communication Interfaces S3(C)“.
During installation of the retrofitting module observe the ESD requirements according to EN 61340-5-1.
This means that on location an antistatic wrist strap with an integrated 1 MΩ resistor has to be used which must be
connected to a proper spot: This is either a grounded pipe or – only with an appropriate adapter! – a Schuko plug
grounding socket. The antistatic wrist strap must be worn tightly on the skin of the wrist.
Open the calculator by pulling the clamping bracket at the upper housing´s leading edge up.
Plug the interface module on the right side of the PC board. If there are module cables you have to loosen the
needed number of cable glands and to glide them over the cables. Remove the blind plugs from the cable gland
openings and feed the cables into the calculator.
Protect the calculator against unauthorized opening using one of the numbered adhesive seals enclosed to the
modules. The added bar code label can be used for the purpose of documentation.
7.3 Exchanging the battery
The calculator´s battery is easy to exchange by authorized technical personnel (our replacements only).
Replaced batteries must be disposed of according to relevant environmental regulations.
Open the calculator by pulling the clamping bracket at the upper housing´s leading
edge up. Afterwards protect the calculator against unauthorized opening using one
of the numbered adhesive seals enclosed to the batteries (stick it upon the seal
destroyed). The added bar code label can be used for the purpose of
documentation.
