SIGNAL TYPES PT100 AND THERMOCOUPLE

The 701 can be connected to signal type PT100 or thermocouple. As standard, the 701 is linearized for a PT100
(factory setting). If you are using a thermocouple, the temperature controller needs to be linearized to the chosen
thermocouple type L, J or K.

LINEARIZATION TO SIGNAL TYPES THERMOCOUPLE L, J OR K

To linearize the 701 to signal type thermocouple follow these steps:
1. Press the menu-button to enter the "User level".
2. With the "down" arrow -button go one step down to "Configuration".
3. Press the menu-button to reach the "Configuration"-menu.
4. With the "down" arrow -button go two steps down to menu-item "Analog input".
5. Press the menu-button again to go to measurement input group 2 (Signal type, thermocouple).
Here you can choose between thermocouple types L, J or K.

Fe-CuNi „K"
6. Select your thermocouple type and confirm your selection by pressing the menu-button.

INITIAL STARTING

The thermostat function  Function  Heating is set at the factory.
Relay output K1 is initially inactive at the factory setpoint of 0 °C
Relay output K1 is inactive because the factory setpoint has already been reached or
Note
exceeded at a room temperature of 20 °C
For commissioning, the controller must first be configured beyond the factory settings.
For this purpose, the setpoint must be defined and the switching differential must be set. In addition, an upper and
lower alarm value can be set. The alarm is indicated in the controller display when these values are exceeded or
undershot.
To set the setpoint or the switching differential, proceed as follows (for an overview, see Figure 8)
1. Press the menu key to enter the "User level".
2. Press the down arrow key once to select the "Configuration" entry.
3. Press the menu key to enter the "Configuration" menu.
4. Press the down arrow key to select the "Setpoint 1" or "Switching differential" menu item.
5. Press the menu key again to enter the setpoint or the switching differential.
