Digital Inputs
With the Digital Inputs DI1...DI4 (for mains voltage)
a number of tasks can be triggered which can be set
on the Assignment Page (h).
If the input is not required, it should be switched off.
Whether the digital input reacts on voltage, (Active),
or on no voltage, (Passive), is dependent upon the
selected task:
---
= The digital input is switched off
L(1
= Load Limitation 1 (r11) will be released (act)
L(2
= Load Limitat. 2 (r12) will be released (pass.)
FbL
= Forced Backrun of the stages (passive)
fbK
= Forced Backrun of the stages (active)
dnL
= Night Operation, i. e. Night Setpoint (passive)
dnK
= Night Operation, i. e. Night Setpoint (active)
LFL
= external suction pressure fault (passive)
LFK
= external suction pressure fault (active)
KFL
= external high pressure fault (passive)
KFK
= external high pressure fault (active)
r1
= Feedback signal 1 (from motor, active)
r2
= Feedback signal 2 (from motor, active)
r3
= Feedback signal 3 (from motor, active)
r4
= Feedback signal 4 (from motor, active)
Real Time Clock / Time Synchronization /
Night Mode
The built-in real time clock has a buffer for max. 10
days without mains voltage. Date and time can be
set by "
P80
"..."
P85
" (Mode Page).
By default, a GMT +01:00 is set (
P71
= 60 min.),
which is standard for the Central European Area.
If the product is used in other countries, this value
can be changed.
Summer/Winter Switch - Time Zones
An automatic summer/winter switch "
P70
= EU"
(Mode Page) considers the current EU-rules from
1996 (EU 96), but can also be switched off or set
as needed.
The current setting, (Summer/Winter), can be viewed
at ‚
P69
‘.
Variable Time Zones
The function for Variable Time Zones can be
activated by "
P70
= tun" and is adaptable by the
parameters "

.. (Fact. Set. 3, 3 o'clock)
The hour of the end of the summertime
The shift to the summertime (= daylight saving time)
respective winter time is set by the time setting which
is active at this time.
Time Synchronisation
In the Mode Page the parameter
P20
determines if
date and time will be transmitted to the connected
Cold Storage Controllers.
Second Setpoint Mode
See page 12.
Relay Outputs
A specific function can be assigned to each relay
output, including the SSR relay outputs, via ‚
h01
...
h09
‘. Any of these relays can also be switched on
manually.

permanent

Control with the Analogue Output
(P-Controller, HP)
To adapt to the process, the following parameters
can be set on the Setpoint Page.
d20
=
P Analogue Output - Output Delay
d21
=
P Analogue Output - Step Size
This function can be used for triggering of a frequency
converter.
The P-range results from the switching point of forerun
and backrun. With an active P-controller only a forerun
signal will be generated if the analogue output has
reached its maximum value.
Inversely a backrun signal will be generated only, if
the analogue output has fallen to 0%.
By the 'Night Limitation' setpoint (
d11
) the maximium
value of the analogue output while night operation
can be limited.
Function Control
L96
(Actual Values Page) shows the current output
signal as %-value of the selected range.
Analogue Output
The analogue output can be used for regulation
purposes or forwarding of the actual value. The signal
is available as a DC-Voltage (010) or a DC-Current-
Signal (420), set by "
h40
" (Assignment Page).
Parameter "
L96
" (Actual Values Page) shows the
current output signal as a %-part of the selected
range. Parameter "
h41
" (Assignment Page)
determines the behaviour of the output:

Control with the Analogue Output
(PI controller, SP)
To adapt to the process, the following parameters
can be set on the Setpoint Page. For working with
extreme dead times, the controller allows an additional
output delay:
r13
=
PI proportional band/range, located
symmetrically around the setpoint
r14
=
PI integral time
r15
=
PI output delay
r16
=
PI step size
If a demand comes from the controller which causes
the analogue output to rise or fall, then an Output
Delay (
r15
, Setpoint Page) will be started. Within this
time period, the output signal changes only by a set
percentage rate (Step Size,
r16
).
If "
r16
" is set to "100%"
and
"
r15
" to "0", then the
function is de-activated.
These parameters apply to all PI functions which can
be realized by the analogue output.
