6.15 Error behaviour / display
The controller activates its error behaviour when one of the following events occurs:
1. Display SBE1 means: At input 1 there
is a sensor break or current below 1mA
at 4-20mA input or voltage below 0.25V
at 1-5V input.
2. Display SB2E means: At input 2,
sensor breakage or current below 1mA
at 4-20mA input or voltage below 0.25V
at 1-5V input if PV2, P1-2 or P2-1 is se-
lected at parameter PVMD or PV2 at
SPMD.
3. Display ADER means: There is an
error in the A/D converter.
Output 1 and 2 start the error behaviour if
one of the following events occurs:
1. during switch-on (for 2,5 sec.)
2. the controller goes into error mode
3. the controller goes into manual mode
4. The controller goes into calibration
mode
Output 1 Error behavior (when activated)
1. If output 1 is set to proportional rules (PB1 ≠ 0) and BPLS is set in O1FT, then
output 1 goes to bumpless transfer. Means, to control output 1 the average of
MV1 is taken.
2. When output 1 is set to proportional controls (PB1 ≠ 0) and 0 to 100.0% is set
for O1FT, then output 1 goes to error transmission. Means that the set value of
O1FT is used to control output 1.
3. If output 1 is set to ON-OFF rules (PB1 = 0), then output 1 goes OFF when
O1FT = REVR, when O1FT = DIRT, output 1 goes ON.
Output 2 Error behavior (when activated)
1. If OUT2 = COOL and O2FT = BPLS, output 2 goes to bumpless transfer.
Means, to control output 2 the average of MV2 is taken.
2. If OUT2 = COOL and O2FT = 0 to 100%, then output 2 goes to error
transmission. This means that the set value of O2FT is used to control
output 2.
Alarm 1 Error behavior
Alarm 1 is activated when the controller enters the error mode, at Alarm 1 becomes
ON or OFF depending on the setting of A1FT.
Exceptions: If A1FN = LB or SENB, alarm 1 is switched ON independently of A1FT.
If A1FN = TIMR, no error is output on alarm 1.
