Kamstrup MULTICAL 402, Installation & Maintenance Instructions Manual

Page: 8 / 28

2.2 Short direct sensor set
Short direct sensors can be mounted in special ball valves or in special
tee-pipes, both with threads up to R1 and built-in M10 union for the
short direct sensor.
For mounting in existing heating installations with standard angle tees
Kamstrup A/S can supply R½ and R¾ brass nipples fitting the short
direct sensors.
Short direct sensors can also be fitted directly into all Kamstrup’s
ULTRAFLOW® variants with G¾ and G1 threads on the meter case.
Fasten the brass unions of the sensors lightly (approx. 4 Nm) using a 12
mm face wrench and seal the sensors with seal and locking wire.
3. Information codes ”INFO”
MULTICAL® 402 constantly monitors a number of important functions. If
there is a serious error in the measuring system or installation, a flash-
ing “INFO” is displayed, and an info code can be read by activating the
top front key until the measuring unit displays “INFO”. The info code is
visible as long as the error exists, unless the meter has been specially
configured for ”manual reset of info codes”. When an info code has
existed for an hour, it is saved in the info log.
