10.4 Function and inverting for relay outputs K1 and K2
Various functions can be allocated to the relay outputs K1 and K2
In case of the same function allocation for K1 and K2, these work parallel.
Function description
-- no Function
Relays remain always de-energized
1 K
Operating indication (factory setting for K1)
Operation without fault, reports enable ON / OFF
2 K
Fault indication (factory setting for K2)
At line, motor and controller fault, Sensor fault dependent on
programming, external fault at digital input
3 K External fault separate
With message at digital input (factory setting if terminals bridged)
4 K Limit modulation
when over or falling below limits for modulation
5 K Limit E1
when over or falling below limits for input signal E1
6 K Limit E2
when over or falling below limits for input signal E2
For modes as controller (higher 2.01 ....)
7 K Setpoint Offset
Deviation between actual value and setpoint to high
8 K Group control
Switching on fans depending on modulation
for modes as temperature controller with additional functions ( 2.03) ....)
9 K Heating function
Switch ON point: temperature = Setpoint +/- Offset
Switch OFF point: Temperature around hysteresis over switch ON point
10 K Cooling function
Switch ON point: temperature = Setpoint +/- Offset
Switch OFF point: Temperature around hysteresis below switch ON point
K1 / K2 Inving
The factory preset is the inversion of relay K1 and K2 to „OFF“ (if a function has been programmed).
Switch to „ON“ for inversion (switch-time response depends on the allocated function). Fundamentally, the relays can only
become operative if the electronics’ voltage supply is functioning. At least 2 current phases must be present!
