9DESCRIPTION
The two-step electronic temperature controller 701 has a temperature sensor input for PT100 sensors in two-wire-
technique. The temperature controller is equipped with a short-circuit and sensor break protection. The desired
temperature is selectable via keys. The actual value and the target value are displayed on a dot-matrix LCD. The LCD
display is black and white with backlight and 64 x 80 pixel resolution.
The control function is indicated by a "K1" in the upper left display area. Switching hysteresis, alarm limit values,
zero point correction and various other parameters can be set via program functions.

10 RECEIPT OF GOODS AND STORAGE
Immediately after arrival, remove the controller and eventual accessories carefully from the packing and check
the articles for completeness against the packing list;
Check the goods for any damage during transportation and, if required, inform your shipping insurance
immediately of the damage found.
Note
The controller should be stored in a weather-protected and frost-free area!
10.1 PRODUCT LABEL AND SERIAL NUMBER
The product label with the serial number is placed on the side of the device.
11 INSTALLATION INSTRUCTIONS AND DIMENSIONS
Figure 3 Dimensions and indication of the connection terminals
The controller is designed for mounting on a top hat rail according to DIN IEC 60715.

10 Temperature controller 701 | 1.01.00 www.mc-techgroup.com
Maintain the minimum distance of 20 mm [≈ 0.8”] above and below the controller.
1. So that the release slot can be accessed with a screwdriver from the bottom.
2. So that when dismounting, the device can be swiveled upwards and removed from the DIN rail.
Several devices can be mounted right next to each other without a minimum distance.
12 ELECTRICAL CONNECTIONS
The temperature controller 701 can be delivered with a mains voltage of 230 V 48/63 Hz or 115 V 48/63 Hz.
Warning
A wrong mains voltage can destroy the device. Please ensure that the supply
voltage is identical to the indication on the type plate.
Warning
When setting high-power electrical units with nominal voltages of up to 1000 V,
attention must be paid to the requirements of VDE 0100 together with the
associated standards and stipulations!
A main switch must be provided externally.
The main circuit of the instrument must be equipped with a fuse corresponding
to the nominal voltage (over current protection); for electrical details see technical
data.
The electrical connection is to be made on the terminal screws on the front side of the housing (see Figure 3).
Warning
The nominal capacity of the connected heated line must not exceed 2300 Watt.
1. Connect the temperature sensor PT100 to the terminals 1and 2.
Figure 4 PT100 connection
If a thermocouple is used, terminals 1and 2are connected as shown in Figure 5.
Figure 5 Thermocouple connection

www.mc-techgroup.com Temperature controller 701 | 1.01.00 11
2. Connect the mains voltage terminals identified with L1 and Nto the supply voltage being sufficiently
protected by fuse.
3. Connect the switching contact for ON/OFF for the consumer to the terminals 5/6/7with the functions NO
(normally open) /NC (normally closed) / COM (potential).
Figure 6 Relay output K1 (zero-current state)
4. Optionally, a multipole coupling socket can be mounted externally that will be wired with the temperature
controller according to the pin connection plan (see Figure 6). This enables you to make a simple, easy
servicing connection between the heated sample lines 3/4/5-N/M/H or PSP-4M (-W) by means of the
multipole coupling connector (standard equipment of the heated sample lines) with the temperature
controller.

13 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.
13.1 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.
Linearization Comment Measuring range
Fe-CuNi „L“ DIN 43710:1985-12 -200 bis + 900 °C [-328 to 1652 °F]
Fe-CuNi „J“ DIN EN 60584-1:2014 -210 bis +1200 °C [-346 to 2192 °F]
Fe-CuNi „K“ DIN EN 60584-1:2014 -270 bis +1300 °C [-454 to 2372 °F]
6. Select your thermocouple type and confirm your selection by pressing the menu-button.
14 INITIAL STARTING
The thermostat function Function Heating is set at the factory.
Note
Relay output K1 is initially inactive at the factory setpoint of 0 °C [32 °F].
Relay output K1 is inactive because the factory setpoint has already been reached or
exceeded at a room temperature of 20 °C [68 °F].
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.

14.2 FUNCTIONAL TEST
Principally, it must be checked after the initial starting whether the controller is switching according to the adjusted
values and whether the determined operating temperature is reached.
The first function test has to be effected as follows:
1. Switch on the power supply.
2. After the set point temperature is being reached, the controller cuts the heater off the "K1"
indicator in the display is turned off.
