1.3.3 Obligations of the operators
Carefully read the operation manual before operating the temperature control unit. Please observe
the safety instructions. When operating the temperature control unit, wear appropriate personal
protective equipment (e.g. safety goggles, protective gloves, non-slip shoes).
1.4 General information
1.4.1 Description of workstation
The workstation is located at the control panel in front of the temperature control unit. The work-
station is determined by the customer's connected peripheries. Accordingly, it must be designed
safe by the responsible body. The workstation design also depends on the applicable requirements
of the German occupational health and safety regulations [BetrSichV] and the risk analysis for the
workstation.
1.4.2 Safety devices to DIN 12876
The rating of your temperature control unit is stated on the data sheet in the appendix.

Usually water; other fluids only if non-combustible even within the temperature range of an individual fault.
b)
The temperature control media must have a combustion point of ≥ 65 °C.
c)
The overheat protection can, for instance, can be realized using a suitable fill level sensor or a suitable temper-
ature limiter.
d)
Optional at the choice of the manufacturer.
1.4.2.1 Temperature control units (with heater) with electronic low level sensor
The low level protection operates via a pressure sensor in the fluid circuit. The pump and the ther-
mal fluid provide the required pressure at the pressure sensor. Air in the system (fill level too low,
inadequately vented) prevents the pressure from reaching value specified at the pressure sensor.
Temperature control and circulation are interrupted.
Overtemperature protection (for temperature control units with heater)
There is no longer a need for mechanical tools to set the trigger values of the overtemperature
protection. It is replaced by a software engineering tool. The threshold value for the overtempera-
ture protection can be set only if a code, randomly generated by “Pilot ONE”, is entered correctly. As
with the mechanical tool, accidental settings are thus prevented.
