1. DESCRIPTION
2. SAFETY RECOMMENDATIONS
3. APPLICATIONS
MT-516
e
is a temperature controller for cooling or heating applications. Equipped with a cyclic
timer output, it can also be used as alarm output, with the option of an internal audible alarm (buzzer), or
second cooling or heating stage. Another feature available is the turning off of the control functions,
making the
MT-516
e
operate only as a temperature meter. Through an intelligent function
blocking system, it prevents unauthorized personnel from changing the control settings.
Product conforming to UL Inc. (United States and Canada).
- Check the controller for correct assembling;
- Make sure that the power supply is off and that it is not turned on during the controller installation;
- Read the present manual before installing and using the controller;
- Use adequate Personal Protective Equipmenet (PPE);
- For application at sites subject to water spills, such as refrigerated cabinets, install the protecting vinyl
supplied with the controller;
- For protection under more critical conditions, we recommend the Ecase cover, which we make
available as an optional item (sold separately);
- The installation procedures should be performed by a qualified technician.

Admissible variation in relation to the voltage rating.
(**)
This device can measure and control temperatures of up to 200° C when used in conjunction with a model SB59 silicon
sensor cable (sold separately).
Note:
Sensor cable length can be increased to up to 200 meters by the user by using a PP 2 x 24 AWG cable.
