BLOCK C112. Parameter configuration
Set point SP1 - data input from keys
Set point SP1 - interlocked to external probe (configure)
ERROR/FAULT INDICATION
NUMBERS BLINKING IN DISPLAY
- Situation -
The number 1999 blinks in the display as the actual value, with the
set point value displayed normally.
- Cause -
The real value is not being measured. This means that the upper or lower
limit of the measurement range on analog input 1 (real value) has been exceeded.
- Remedy -
Check the electrical connections and the state of the probe. If the probe
is faulty, the regulator will not indicate the real value of the physical quantity
monitored. This will result in automatic shutdown (failsafe), deactivation of the
self-adapt function and inhibition of manual operation. The response of the
auxiliary contact will depend on the configuration of parameter C113.
- Situation -
The number 1999 blinks in the display as the actual value, with tA
showing in the set point field.
- Cause -
The external temperature is not being measured. This means that the
upper or lower limit of the measurement range on analog input 3 (real value) has
been exceeded.
- Remedy -
Check the electrical connections and the state of the probe. If the probe
is faulty, the regulator will not indicate the real value.
- Situation -
The number 1999 blinks in the display as the actual value, with SP .E
showing in the set point field.
- Cause -
The external set point value is not being measured. This means that the
upper or lower limit of the measurement range on analog input 2 (real value) has
been exceeded.
- Remedy -
Check the electrical connections and the external set point signal. If the
probe is faulty, the regulator will not indicate the real value of the physical quantity
monitored. This will result in automatic shutdown (failsafe), deactivation of the
self-adapt function and inhibition of manual operation.
