A.r.F/ Selection of alarm output function.
Let you assign one of the following functions to each alarm
output: Normal Alarm, HB Alarm, LBA Alarm, Alarm disabled
(OFF logic state). Choose one of the 63 combinations
according to the table:
Ar.F
Output AL1
0
AL1

HB
2
LBA
3

9

10
LBA
11
OFF
12
AL1
13

14
LBA
15
OFF
By setting +0 output AL3 has function AL3
By setting +16 output AL3 has function HB
By setting +32 output AL3 has function LBA
By setting +48 output AL3 is always OFF
Notes:
- The output state can be reversed by setting its alarm to
reverse (code AL for outputs AL1 and AL2 and code Out for
output AL3, in CFG.2 phase)
- The selection for outputs AL2 and AL3 is inoperative in case
of configuration type "relay not present" (see brd code)
- Function "ArF" has priority over function "Out".
Ctr/ Selection of type of PID control and means of switching
from automatic to manual according to table:
Ctr PID control for:
0
Slow process
(ts=8sec)
1
Fast process
(ts=1sec)
2
Slow process
(ts=8sec)
3
Fast process
(ts=1sec)
Notes:
sample time for actions I and D
A fast process is defined as one with main time constant less
than 60 seconds. It is advisable to disable the digital filter on
the input in case of PID for fast processes (see S.tu code in
phase 0).
Hb.F/ Selection of type of HB alarm from 4 different choices:
0 - alarm trips when load current (CT input) drops below limit

set for ON time of MAIN output
1 - alarm trips when ammeter full scale (Hb.S) in main output
OFF time is exceeded by 12%.
2 - alarm trips if one of functions 0 and 1 (described above) is
active. (OR logic between functions 0 and 1)
3 - HB alarm for continuous output (PWM, setting _Ct = -1 or
-2); does not take account of ON/OFF times and presupposes
a special ammeter card with hw integration of load current.
NOTES: disabled if the output power is < 3%
Notes:
- code Hb.F is accessible only with ammeter input card
installed (see brd code) and HB alarm enabled (code Out in
CFG.2)

Add 64 to code to configure the model with input from current
transformer.
Add 128 to code to configure the model with serial
communication CL or 485.
Notes:
- The selected configurations must conform to the instrument's
hardware model. An incorrect selection may cause functioning
not conforming to specifications.
- The brd code can be changed only with jumper S8 closed
(Hardware Configuration / CPU Input Card).
- The brd code is also available in calibration phase.
Notes: The configuration model with serial communication CL
or RS485 in alternative to relé AL2 and AL3 outputs.
