Accessible parameters with key software
Removable terminals connection.
Execution DIN 48 X 96.
Recessed assembly.
Special retaining brackets.
One Pause and one Work Set Point
4 Time Scales
UP / DOWN Timing
Memory
Timing Start in Pause or in Work Mode
START Input Selection
Operating in Automatic or Single Cycle
OUTPUT mode selection

DESCRIPTION OF THE OPERATION
In the Timer type LHP the choice of the scale time is valid for both the timing. Selecting the START departure in Pause or Work and
the timing in UP or DOWN the instrument gets ready in order to work. In Automatic operation the timing begins to the input START
closing. Between the two timings it is possible to execute a programmable intermediate time.

DESCRIPTION OF THE FRONTAL KEYBOARD
ø
YELLOW
The key 'LEFT ARROW' in normal operating phase visualizes, blinking, all the programmings executed without the
limitation of the insertion code. The time of scansion of the programmings is given from the pressure of the same
key. It exits automatically from this phase after 5 sec of the last pressure of the same key.
In programming phase it moves the cursor of the figure towards left of a step, than at the beginning it is on the right
side first one on the. At the end it resumes from the first one to right.
ù
YELLOW
The key 'UP ARROW' in normal operating phase it enter and exit to the Cycle Predeterminator.
In programming phase it increases the value of the blinking figure.
ú
BLUE
The key 'PRG' pressed for 2 sec. allows to enter in the programming phase, visualizing on display C.0000.
In the programming phase, pressing key 'PRG' impulsively, it exits from the programming phase. The instrument
exits automatically from the programming phase, 60 sec. after the pressure of the last key.
û
RED
The key 'ENT/RES' in normal phase of counting has the 'RESET' function, with the modalities to it attributed in the
programming phase.
In programming phase it confirms and memorizes the visualized data and passes to the successive function. If it has
arrived to list end it resumes from the beginning.

SET POINTS PROGRAMMING
For SET POINTS programming access, proceed as follow:
- Press key ‘PRG’ in impulsive mode; on display appears:
0¨0¨20
P. = Time of PAUSE, programmable between 1 cent of second and 9999h59m (depending on
the programmed scale). If programmed = 0 it automatically reprograms itself to 1 sec.
0¨0¨20
Ä
L. = Time of WORK, programmable between 1 cent of second and 9999h59m (depending on
the programmed scale). If programmed = 0 it automatically reprograms itself to 1 sec.
Key ENT confirms the data and passes to the successive programming. In order to exit the programming, press key PRG.
PROGRAMMING OF THE OPERATION PARAMETERS
The programmable parameters are divided in two groups and protect with a 4 figures code.
In order to approach the programming, proceed in the following way:
- Press key
PRG
for about 2 sec. On the display appears:
» 0000
GROUP 1
:
insert code
2357
and press
ENT
.
Ìi9²9
t.i. = Intermediate Time, programmable between 0.0 and 99.9 sec. This time comes
executed, if programmed various from 0, between the PAUSE time and the WORK time).
During the execution of this time the output is not active.
SCÄ 1
SCL. = Time Scale. Selection of the maximum time scale of the timing. It’s possible to choose
between 4 different time scales:
1 = 59m59s99c - 2 = 99h59m59s - 3 = 9999h59m - 4 = 9999s99c
Cæ UP
Cæ dæ
Count UP / DOWN / Superior.
Count = Up: the timer gets ready to visualize the timing in increasing way (UP), starting from
zero up to the programmed value of set point.
Count = dn: the
timer
gets ready to visualize the
timing
in decreasing way (DOWN), starting
from the programmed value of set point to zero.
Stê è
Stê Ä
Start in PAUSE or in WORK mode.
Str. = P. : the cycle starts executing the PAUSE time
Str. = L. : the cycle starts executing the WORK time
PROGRAMMING OF THE OPERATION PARAMETERS
The programmable parameters are divided in two groups and protect with a 4 figures code.
In order to approach the programming, proceed in the following way:
- Press key
PRG
for about 2 sec. On the display appears:
» 0000
GROUP 3
:
insert code
3210
and press
ENT
.
9999
Û
c. = CYCLES PREDETERMINATOR, programmable between 0 and 9999; with this parameter
is possible to program how many cycles of PAUSE/WORK the instrument must execute. At the
end of the cycles number, the sequence comes interrupt. To restart the sequence it is
necessary to reset the predeterminator. If the value is programmed = 0 the function is excluded
and the sequence goes to infinite. Pressing the
ù
key the display shows the decreasing value
of the predeterminator; pressing another time the key the display shows the current timing.

Active or excluded memory.
This parameter allows to program the saving of the current counter value during the power off
the instrument.
MEM.on. = memorization of the count during the power off. When power on the instrument the
display will visualize the last present value in the power off phase.
MEM.of. = excluded memorization of the count; every time that the instrument comes powered
off and then powered on the count comes lost and the instrument restart always from the initial
condition.

F
RESET Key ON / OFF; this programming enables and disables the RESET function of frontal
key RES during the operation of the timing.
RES.on = RESET function of key RES enabled
RES.of. = RESET function of key RES disabled

Programming of the START Input.
This programming allows to Start the timing in three different modes:
In. I. = Impulsive Mode; the timing starts with the impulsive closing of the START input.
In. C. = Continuously Mode; the timing starts with the closing of the START input; the timing
is interrupted every time the START input comes opened.
In. S. = Start/Stop Mode; the timing starts with the impulsive closing of the START input and it
stops to the subsequent closing. Closing another time the input the timing resume and it stops
to the subsequent closing.
CYÄ ¹
CYÄ Í
Programming of the PAUSE/WORK Cycle in Automatic or Single mode
This parameter allows to program the execution of the PAUSE/WORK Cycle in Continuos
mode (AUTOMATIC) or in Single mode (UNIQUE). With the AUTOMATIC programming the
cycle goes to infinite (or for many cycles how many have been programmed with the
programming under code 3210); with the Single programming (UNIQUE) the cycle is executed
one time only and restart after a reset.
CYL. A. = execution of the cycle timing in continuos mode.
CYL. U. = execution of the cycle timing one time only.
0íÈ î
0íÈ ÷
Programming of the OUTPUT RL1. This parameter allows to activate the RL1 relay
during the timing
î
or at the end
÷
of the timing.
Ou.P.
î
= Activation of the RL1 relay during the timing
Ou.P.
÷
= Activation of the RL1 relay at the end of the timing
¹È È
¹È ê
Activation mode of the programmed parameters.
With this programming is possible to activate the executed programmings directly to the exit of
the programming or, when exited of the programming, after a RESET (with frontal key or from
rear input)
A.P. = P. Activation of the parameters to the exit of the programming.
A.P. = r. Activation of the parameters to the exit of the programming after a RESET.
