Notes: 1.
The instrument can receive the start, hold and
reset timer commands from
button, digital
inputs and/or serial link.
2.
A HOLD command can suspend the time count.
[84] t.F= Independent timer function
Available:
Always.
Range:
nonE = Timer not used;
i.d.A = Delayed start timer;
i.uP.d = Delayed start at Power ON;
i.d.d = Feed-through timer;
i.P.L = Asymmetrical oscillator with start in OFF;
i.L.P = Asymmetrical oscillator with start in ON.
[85] tr.u - Time Engineering unit
Available:
When [84] Tr.F is different form
nonE
.
Range:
hh.nn = Hours and minutes;
nn.SS = Minutes and seconds;
SSS.d = Seconds and tenth of seconds.
Note:
When the timer is running, you can see the value of
this parameter but you can NOT modify it.
[86] tr.t1 - Time 1
Available:
When [84] Tr.F is different form
nonE
.
Range: •
When [85] tr.u = hh.nn
00.01... 99.59;
•
When [85] tr.u = nn.SS
00.01... 99.59;
•
When [85] tr.u = SSS.d
000.1... 995.9.
[87] tr.t2 - Time 2
Available:
When [84] Tr.F is different from
nonE
.
Range: •
When [85] tr.u = hh.nn: 00.01... 99.59 + inF;
•
When [85] tr.u = nn.SS: 00.01... 99.59 + inF;
•
When [85] tr.u = SSS.d: 000.1... 995.9 + inF.
Note:
Setting [87] tr.t2 = inF, the second time can be stopped
by a reset command only.
[88] tr.St - Timer status
Available:
When [84] Tr.F is different form
nonE
.
Range: •
run =
Timer Run;
•
HoLd =
Timer Hold;
•
rES =
Timer reset.
Note:
This parameter allows to manage timer execution by a
parameter (without digital inputs or
button).

PrG Group - Programmer function parameter
These instruments are able to perform a set point profile
composed by 4 groups of 2 steps each (8 step total).
The first step is a ramp (used to reach the desired set point),
the second is a soak (on the desired set point).
When a RUN command is detected, the instrument aligns
the operative set point to the measured value and starts to
execute the first ramp.
In addition, each soak is equipped with a wait band which
suspends the time count when the measured value goes out
of the defined band (guaranteed soak).
Moreover, for each segment it is possible to define the status
of two events. An event can drive an output and make an
action during one or more specific program steps.
Some additional parameters allow to define the time scale,
the automatic RUN conditions and the instrument behaviour
at program end.
Notes: 1.
All steps can be modified during program execution.
2.
During program execution the instrument stores
the segment currently in use and, by a 30 minutes
interval, it stores also the elapsed time of the soaks.
If a power down occurs during the program execu-
tion, at the next Power ON the instrument is able
to continue the program execution starting from
the segment in progress at power down and, if the
segment was a soak, it is also capable to restart
from the soak time minus the stored elapsed time.
In order to obtain this features, the
[120] dSPu -
Status of the instrument at Power ON
parameter
must be set to
AS.Pr
.
If the [120] dSPu is different than
AS.Pr
the stor-
ing function will be hinibited.

Program RUN
[89] Pr.F = Programmer action at Power ON
Available:
Always.
Range:
nonE = Program not used;
S.uP.d = Start at Power ON with first step in Stand-by;
S.uP.S = Start at Power ON;
u.diG = Start at RUN command detection only;
U.dG.d = Start at RUN command detection with first
step in stand by.
[90] Pr.u - Soaks Engineering units
Available:
When [89] Pr.F is different from
nonE
.
Range:
hh.nn = Hours and minutes;
nn.SS = Minutes and seconds.
Note:
During program execution, this parameter cannot be
modified.
[91] Pr.E - Instrument behaviour at the
End of program execution
Available:
When [89] Pr.F is different from
nonE
.
Range:
cnt =
Continue (the instrument will use the set
point of the last soak until a reset command
is detected);
SPAt = Go to the set point selected by [79] SPAt
parameter;
St.bY = Go in stand by mode.
Notes: 1.
Setting [91] Pr.E = cnt the instrument operates as
follows: at program end, it will use the set point of
the last soak.
When a reset command is detected, it goes to
the set point selected by [79] SPAt parameter.
The transfer will be a step transfer or a ramp
according to the [82] SP.u (max. rate of rise for
positive set point change) and [83] SPd (max. rate
of rise for negative set point change).

Setting [91] Pr.E = SPAt the instrument goes
