10.7.33 Dry-running protection (4.4.1)

Fig. 60

Dry-running protection

Description

Dry-running protection is one of the most important monitoring
functions, as bearings and shaft seal may be damaged if the
pumps run dry. Grundfos thus "requires" dry-running protection in
connection with Hydro MPC booster sets.

The function is based on monitoring of the inlet pressure or the
level in a possible tank or pit on the suction side.

Level switches, pressure switches or analog sensors signalling
water shortage at a set level can be used.

There are three different methods for detection of water shortage:

•

Pressure switch on suction manifold or float switch/electrode
relay in the supply tank.

•

Measurement of inlet pressure in the suction manifold by
means of an analog pressure transmitter.

•

Measurement of level in the supply tank by means of an ana-
log level transmitter.

If a pressure switch or pressure transmitter is fitted on the suction
manifold, the relevant function has been selected and set.

10.7.34 Dry-running protection with pressure/level switch

(4.4.1.1)

Fig. 61

Dry-running protection with pressure/level switch

Description

Dry-running protection can take place by means of a pressure
switch on the suction manifold or a level switch in a possible tank
on the suction side.

When the contact is

open

, the CU 351 will register water

shortage after a time delay of approx. 5 sec. It is possible to set
whether the indication is to be just a warning or an alarm stopping
the pumps.

In the display it is possible to set whether restart and reset of the
alarm is to be automatic or manual.

Setting range

•

Selection of digital input for the function.

•

Reaction in case of water shortage: Warning or alarm + stop.

•

Restart: Manual or automatic.
