Design and principle of operation
3 Design and principle of oper-ation
See Fig. 2.The safety temperature monitor (STM) oper-ates according to the liquid expansion prin-ciple. The temperature sensor (12), capillary tube(9)andoperatingelement(8)arefilledwith an expansion liquid.
The temperature-dependent change in vol-ume of the liquid in the bulb sensor (12) causes the piston in the operating element (8) to move. As a result, the pin of the oper-ating element (7) moves the plug stem (5) with the plug (3). The temperature limit can be adjusted by a key (10). This limit value is indicated on the dial (11).
The safety temperature monitor closes the valve when the temperature reaches the ad-justed temperature limit. The safety tempera-ture monitor resets itself automatically when the temperature has fallen to a value of ap-prox.5 Kbelowtheadjustedlimit.
Fail-safe positionThe spring mechanism in the operating ele-ment is released when the capillary tube breaks or when there is a leak in the sensor. It moves the plug stem (5) with the plug (3) over the pin (7) and closes and locks the valve.
The adjusted limit temperature must have a minimum temperature difference of 15 K to the set point of the temperature regulator.

5.6 Start-up
Risk of personal injury due to process me-dium escaping under pressure.First start up the regulator after mounting all parts.
Note
DANGER!
Risk of burn injuries due to hot or cold com-ponents and pipelines.Depending on the process medium, valve components and pipelines may get very hot or cold and cause burn injuries. − Allow components and pipelines to cool down or heat up. − Wear protective clothing and safety gloves.
Malfunction and damage due to adverse ef-fects of weather conditions (temperature, hu-midity).Do not install the safety temperature monitor outdoors or in rooms prone to frost. If such a location cannot be avoided, protect the reg-ulator against freezing up if the process me-dium flowing through the valve can freeze up. Either heat the regulator or remove it from the plant and completely drain the re-sidual medium.
Risk of the valve being destroyed by steam hammering. − Drain off any condensate in the pipeline. − Vent the plant.
Î Fill the plant very slowly with the process medium on start-up.
Once the safety temperature monitor is mounted onto the valve, it can be put into operation.

Î Avoid pressure surges.
5.6.2 Steam Î Completely drain and dry steam lines to prevent water hammering.
Î Slowly allow the steam to enter the plant to ensure that the pipes and valves warm upevenlyandtoavoidexcessiveflowvelocities.
Î Beforethefullcapacityisreached,drainoff the start-up condensate.
Î Make sure that the air contained in the plant escapes as quickly as possible.
Î Open the shut-off valves slowly prefera-bly starting from the upstream pressure side.
Î Avoid pressure surges.
6 OperationSee Fig. 2.
6.1 Adjusting the limit temperature
To adjust a different limit temperature in the safety temperature monitor, proceed as fol-lows:
1. If the optional leading screw (13) is used, unscrew it upwards.
2. Use the key (10) to adjust the new limit value according to the dial. Slowly turn the key clockwise () to increase the limit temperature and counterclockwise () to reduce it.
3. Liftoffthekey(10)andscrewthelead-ing screw back into the housing, if appli-cable.
When the safety temperature monitor is com-bined with a Type 2231 to 2235 Control Thermostat, make sure that there is a mini-mum difference of approximately 15 K be-tween the adjusted limit temperature of the safety temperature monitor and the set point temperature of the control thermostat.
6.2 Sensor failureIndication that the sensor is defectiveIn the event of a defective sensor (e.g. leak-age in the sensor system), the green signal pin (8.2) disappears into the housing. In the normal state, the pin sticks out over the hous-ingbyapproximately1.5 cm.
Note
24 EB 2043 EN
Operation
6.3 Correcting the limit value dial
Due to ambient and temperature conditions, the adjusted limit temperature might not be the same as the temperature indicated by the reference thermometer.
To correct, proceed as follows:
1. Undo the screw labeled "Korrektur" on the back of the dial housing (14).
2. Turn the entire dial housing until the dial shows the same temperature as the refer-ence thermometer.Turn clockwise () to increase the limit and counterclockwise () to reduce it (viewed from the front with the dial hous-ing on top).A360°turncorrespondstoalimitchangeofapprox.1.5 K.
6.4 Fine adjustment of the limit temperature
Incaseyouwanttomakefineadjustmentstothe safety temperature monitor or the limit value deviates, proceed as follows:
Fine adjustment using a heating bath1. Remove the sensor from the pipeline (see
section 9.1).
2. Adjust the safety temperature monitor approx.10 Kbelowtherequiredlimit(seesection 6.1).
3. When a control thermostat is mounted on the safety temperature monitor, adjust
thelimittemperaturetoapprox.10 °Cabove the limit temperature.
4. Immerse the sensor of the safety tem-perature monitor completely into the heating bath with the correct tempera-ture.
5. Check whether the safety temperature monitor has closed the valve (after ap-prox.5 min.).Thetravelindicator(8.3)must be at '0'.
6. When the valve is still open: slowly turn the key (10) at the safety tem-perature monitor clockwise () to in-crease the limit until the valve closes.
When the valve is closed: turn the rotary knob clockwise () three more times.
7. To calibrate the limit reading to the limit temperature, perform a correction (see section 6.3).
8. When a control thermostat is mounted, readjust it to the required set point.
9. Reinstall the sensor into the pipeline (see section 5.3).
Fine adjustment using a thermometer installed in the plant1. Adjust the limit temperature of the safety
temperaturemonitortoapprox.10 Kbe-lowtherequiredlimit(seesection 6.1).
2. When a control thermostat is mounted on the safety temperature monitor, adjust thelimittemperaturetoapprox.10 °Cabove the limit temperature.
EB 2043 EN 25
Servicing
3. Read the resulting temperature at the thermometer installed in the plant (after approx.5 min.).
4. When the limit temperature is still too low: slowly turn the key (10) at the safety tem-perature monitor clockwise () to in-crease the limit until the temperature at the thermometer reaches and remains at the limit temperature.
After the temperature reaches the limit temperature: turn the rotary knob clockwise () three more times.
5. To calibrate the limit reading to the limit temperature, perform a correction (see section 6.3).
6. When a control thermostat is mounted, readjust it to the required set point.
7 ServicingThe safety temperature monitor does not re-quire any maintenance. Nevertheless, it is subject to natural wear, particularly at the soldering.
Risk of personal injury due to residual pro-cess medium in the valve.While exchanging the safety temperature monitor, residual process medium can es-cape and, depending on its properties, may lead to personal injury, e.g. (chemical) burns.
WARNING!
Wear protective clothing, safety gloves, and eyewear.
Risk of burn injuries due to hot or cold com-ponents and pipeline.Valve components and the pipeline may be-come very hot or cold. Risk of burn injuries. − Allow components and pipelines to cool down or heat up. − Wear protective clothing and safety gloves.
Risk of damage to the valve or safety tem-perature monitor due to excessively high or low tightening torques.The connection between valve and safety temperature monitor must be tightened with a certain tightening torque. Excessively tight-ened torques lead to parts wearing out quicker. Parts that are too loose may cause leakage.Observe the specified tightening torques.
The safety temperature monitor was checked by SAMSON before it left the factory. − Certain test results certified by SAMSON lose their validity when the safety tempera-ture monitor is opened. − The certification according to DIN EN 14597 loses its validity when the safety temperature monitor is opened.
