Panel-mounted Thermostats, EM Series

with 1, 2, 3, or 4 single-pole snap-action switches

Approvals/approval marks (see "Technical data")

DGRL

97/23/EG

Brief description

Thermostats control and monitor thermal processes. The devices of the EM series are available

as temperature controllers TR, temperature monitors TW, temperature limiters TB, safety tem-

perature monitors STW (STB), and safety temperature limiters STB. In the event of a malfunc-

tion, the STB switches the monitored machine to a safe operating status.

Panel-mounted thermostats operate according to the fluid expansion principle – a microswitch

is used as an electrical switching element.

Special features

• Temperature controller TR and temperature monitor TW

• Safety temperature limiter STB

• Tested according to DIN EN 14597

• Pressure Equipment Directive 97/23/EC

Switching function

Temperature controller TR and temperature monitor TW

If the temperature on the temperature probe exceeds the setpoint value, the microswitch is ac-

tivated by the transmission mechanics and the electrical circuit is opened or closed. If the tem-

perature falls below the selected setpoint (by the amount of the switching differential), the

microswitch is reset to its initial position.

Restart lock for temperature limiter TB and

safety temperature limiter STB

If the temperature on the temperature probe exceeds the set limit value, the electrical circuit is

opened and the microswitch is mechanically locked.

The microswitch can be manually unlocked once the temperature has dropped by approx. 10 %

of the scale range (approx. 15 % with a limit value setting >+350 °C).

For limit values exceeding 120 °C, the limit value set in the STB must be secured against incor-

rect adjustment (e.g. by a seal).

Self-monitoring for the safety temperature limiter STB

and safety temperature monitor STW (STB)

If the measuring system is destroyed (i.e. if the expansion fluid leaks), the pressure in the dia-

phragm of the STB and STW (STB) drops and permanently opens the electrical circuit. Unlock-

ing is then no longer possible.

When the probe has cooled down to a temperature below approx. -20 °C, the electrical circuit is

also opened. However, it automatically closes again when the temperature rises above -10 °C.

Use of the safety temperature monitor STW as a safety temperature limiter STB

The circuitry used with the thermostat must comply with DIN EN 14597 and VDE 0631.
