3.3 Monitoring Equipment
The following applies to the monitoring equipment of the pump:
• The stator incorporates thermal contacts that are connected in ser-
ies that activate the alarm at overtemperature.
• The thermal contacts open at 125°C (257°F).
• Ex-approved pumps must have thermal contacts that are connected
to the control panel.
• The sensors must be connected to either the SMR 311 monitoring
equipment or equivalent equipment.
• The monitoring equipment must be of a design that makes auto-
matic restart impossible.
• Information in the junction box shows if the pump is equipped with
optional sensors
Optional sensors
LD LD is a miniature float switch for detection of liquid in the stator
housing. Due to its design, it is best suited for pumps in a vertical
position. The LD sensor is installed in the bottom of the stator
housing.
3.4 The data plate
The data plate is a metal label that is located on the main body of the
products. The data plate lists key product specifications. Specially ap-
proved products also have an approval plate.
