8.3.2 Function analog Input 2 (Analog IN 2 ) second Sensor, external Setpoint, extern manual operation
The function is automatically jointly programmed in operating modes using 2 sensors. The second analog input is thus
allocated and additional function allocations are not possible.
Modes with two sensors
2.04 E2 Function at 4E preprogrammed = comparison value with control to higher temperature
alternative: average of 2 measuring points for this must be reprogrammed on function 3E
preprogrammed sensor Typ TF
2.05 E2 Function at 5E preprogrammed = regulation on difference temperature between sensor 1 and sensor 2.
preprogrammed sensor Typ TF
Possible functions with a free analog input 2 (Analog In 2)
External Setpoint defaults or external speed setting in manual operation with a 0-10 V (0-20 mA, 4-20 mA) signal is
possible on the „E2" and „GND" terminals. Correspondingly insert jumpers E2.1 and E2.2 for analog IN 2 and configure
E2 in base setup.
For potentiometer analog OUT 1 (terminal „A“), program to function 1A (factory setting) = +10 V F IO Setup: Analog
output function.
External Setpoint via external signal (0-10 V, 0-20 mA, 4-20 mA) instead of „Setpoint 1“
The „External Setpoint“ function must be activated in base setup 1E
for E2 function; Set Intern 1 then has no function. A
switchover „Ext. Setpoint“ / „Set Intern 2“ is still possible.
0-10 V (4-20 mA, 0-20 mA) Setting value = 0-100 % sensor measurement range, with temperature regulation using
passive temperature sensor model TF.. -27..75° C.
The active external Setpoint value is displayed in the info menu group.
External speed setting in manual operation (F IO Setup Internal / External).
The „External manual operation“ function must be activated in the basic settings 2E
for E2 function. Switchover between
settings on the device and external manual operation via the digital input (F IO Setup: Internal / External).
