3.7 Display via analog output
(only for ...H RL1 and ...H RLP1)
The following variables are output at the analog output (e.g. when an
external measuring instrument is connected):
Load current (highest phase current from L1, L2, L3)
Load voltage (highest conductor voltage)
Effective power (total power) (only with ...H RLP1)
Additional variables (can be selected via PC/bus, e.g. mains voltage
setpoint etc.)
The user must configure which variable is to be output at the analog
output, (see page 41, Control mode / Analog output). The analog
output can also be used as a setting aid for potentiometer settings
(see page 44, Potentiometer).
3.8 Error and status messages
The Thyro-A has internal error and status messages. The THYRO-
TOOL FAMILY can be used to configure the consequences. The user
can define what the reactions are to be in the event of a particular
message. Possible reactions that can be set are blocking the load
current (pulse inhibition) and an output at fault signalling relay K1
(only for ...H RL1 and ...H RLP1). The working principle can also be
set at fault signalling relay K1. Basic error messages that make ope-
ration of the device impossible always result in pulse inhibition being
actuated or fault signalling relay K1.
