Connection Of Power Supply; Battery Supply; Mains Supply Modules - Kamstrup ULTRAFLOW 54 Technical Description

TECHNICAL DESCRIPTION

7.8 Connection of power supply

®
If ULTRAFLOW is connected via Pulse Transmitter or Pulse Divider, ULTRAFLOW
module/battery in the Pulse Transmitter/Pulse Divider.
7.8.1

Battery supply

Pulse Transmitter/Pulse Divider is fitted with a D-cell lithium battery with connector. The battery plug is connected
to the output module.
Optimal battery lifetime is obtained by keeping the battery temperature below 30 °C, e.g. by wall mounting the
Pulse Transmitter/Pulse Divider.
The voltage of a lithium battery is almost constant throughout the lifetime of the battery (approx. 3.65 V).
Therefore, it is not possible to determine the remaining capacity of the battery by measuring the voltage.
The battery cannot and must not be charged and must not be short-circuited.
The battery supply may only be replaced by a corresponding lithium battery with connector from Kamstrup A/S.
Used batteries must be handed in for approved destruction, e.g. at Kamstrup A/S. (See Kamstrup document 5510-
408, "Lithium batteries - Handling and disposal").
7.8.2

Mains supply modules

The mains supply modules are protection class II and are connected to the output module via a small two-wire
cable with plugs. The modules are powered via a two-wire mains supply cable (without earth connection) through
the cable connector of the Pulse Transmitter/Pulse Divider. Use supply cable with an outer diameter of maximum
10 mm and ensure correct stripping of insulation as well as correct tightening of cable connection (see paragraph
7.8.4).
Max. permitted fuse: 6 A
230 VAC
This PCB module is galvanically separated from the mains supply and is
suitable for direct 230 VAC mains installation. The module includes a
double-chamber safety transformer, which fulfils double-isolation
requirements when the cover is mounted on the Pulse Transmitter/Pulse
Divider. Power consumption is less than 1 VA/1 W.
National regulations for electric installations must be observed. The 230
VAC module can be connected/disconnected by the district heating
station's personnel, whereas the fixed 230 VAC installation to the main
electrical panel must be carried out by an authorized electrician.
24 VAC
This PCB module is galvanically separated from the 24 VAC mains supply
and is both suitable for industrial installations with joint 24 VAC supply
and individual installations, which are supplied by a separate 230/24
VAC safety transformer in the main electrical panel. The module includes
a double-chamber safety transformer, which fulfils double-isolation
requirements when the cover is mounted on the Pulse Transmitter/Pulse
Divider. Power consumption is less than 1 VA/1 W.
National regulations for electric installations must be observed. The 24
VAC module can be connected/disconnected by the district heating
station's personnel, whereas the fixed 230/24 VAC installation in the
main electrical panel must only be carried out by an authorized electrician.
Note: This module cannot be supplied by 24 VDC (direct current).
