2.5 Posizioni commutatore RSW
With the selector in a position other than 0, the Ready signal (Pos.CN14) is normally deactivated and
reactivated momentarily during the execution of a specific command.
The Red LED near the RSW selector shows the position of the selector itself:
The always-on LED corresponds to the position 0, while it executes a flash sequence corresponding to the
number of other selected positions.
(*) Sensor pressure value and automatic setting of overload pressure display
(**) The DSP1-2 display turns off after 10 s in the absence maneuvers
(***) Switching the RSW selector in 0 position and pressing the S1 button the command is deleted
2.6 Wi-fi connection (Optional)
To use a Wi-Fi device for managing parameters, it is necessary to install on your Smartphone a
dedicated application named Hevos OMARLIFT, which is available on Google Play Store and Apple
Store.
-Switches the RSW selector in the position 2, the display will then indicate [UF]
-Wait until the LD32 blu LED is fixed ON
-Search your device and connect the Wi-Fi whose name corresponds to the network identifier indicated
in the 499 parameter the name of serial number (ex. 16187901)
-Start the application and when the login key is required, enter the name of Wi-Fi network (ex.
16187901).
With the RSW selector in the position number 2 you can change the parameters, otherwise with the RSW
selector in others position, you can only view the parameters.
If the RSW selector is not in the position number 2, the LD32 blue light and the WIFi network fall when there
is no connection for more that one minute.
However, remember to return to the position 0 of the switch RSW.
2.7 SD-CARD parameters and records recovery
To save the parameters via SD CARD must use a Micro SD 2 to 16 GB already formatted FAT 32.
-Switch the RSW selector in position 7, the display will then show [oc] and will turn on (ON) Yellow
LED LD35.
Records Recovery (200302 softwar version and higher)
-Then press S1 button, the display will then show [Su] after performing an upstroke or [Sd] after
performing a downstroke, once and the Yellow LED will start flashing (ON-OFF) until the completion
of the writing of the records on the SD card.
If present in memory, both the upstroke and downstroke recording will be saved.
Parameters Recovery
-Then press S2 button, the display will then show [SP] once and the Yellow LED will start flashing (ON-
OFF) until the completion of the writing of the parameters on the SD card.
Both the saving of the recordings and that of the parameters, resets the SCH001 card, with indication [--] on
the display, which will therefore lose the recordings of upstroke and downstroke into memory.
The file containing the parameters on the SD card is named with the number corresponding to network ID,
stored in the 499 parameter, with PAR extension (ex. 16187901.PAR) for the parameters, and UPR and DWR
extensions for the upstroke and downstroke records, with the 31/12/2097 generic creation date.
Then the display will show [00] and the Yellow LED will turn off (OFF) and the Green LED executes a blinking
(ON-OFF-ON).
After the display shows [oc] and will turn on again (ON) LED Yellow.
However, remember to return to the position 0 of the switch RSW.

2.8 SD-CARD parameters loading
To read the parameters from SD CARD must use a Micro SD 2 to 16 GB, formatted FAT 32.
The card must contains the file with the number corresponding to network ID stored in the 499 parameter and
PAR extension (ex. 16187901.PAR) with the data to be loaded.
-Switch the RSW selector in position 5, the display will then show [Ic] and will turn on (ON) Yellow
LED LD35.
-Then press S2 button once and the Yellow LED will start flashing (ON-OFF) until the completion of
parameters loading from the SD card.
-Then the display will show [00] and the Yellow LED will turn off (OFF) and the Green LED executes a
blinking (ON-OFF- ON).
After the display shows [Ic] and will turn on again (ON) LED Yellow
However, remember to return to the position 0 of the switch RSW.
2.9 Overload pressure automatic setting
It is possibile to put automatically the overload pressure in the P108 parameter, with the RSW selector in
position = 1, which is normally displayed actual pressure value that is detected by the sensor.
There are two input modes:
-The first is to place the load in the cabin of the overload swiching.
In this case the parameter P111, which stores the nominal load rate, must contain the value 0 and the
acquisition in the parameter P108 will be that of pressure sensor reading in the current condition.
-The second is to acquire the overload value with empty cabin.
In this case, the P111 parameter must contain the value of the nominal laod rate and therefore will be
entered in parameter P108, the calculated pressure, according to the characteristics given in the
parameters P101, P103, P104 and P109, whereas as overload, the load rate increased by 10%, with
a minimum of 75 kg (165 lb).
In both cases, pressing the S1 button toggles the insert mode, where the display shows [AP], and then pressing
the S2 button is acquired or calculated, in the P108 parameter, the overload value.
Instead using the hand terminal, you must set the parameter P711 = 1, the first time to switch to insert mode
[AP], and the second time the parameter P711 = 1, to acquire or calculate, in the P108 parameter, the overload
value.
However, remember to return to the position 0 of the switch RSW.
2.10 Software updating procedure
Before the upgrade of board software should save the current operating parameters (Ex. SD-CARD
PARAMETERS RECOVERY).
-To update the software must be present on SD CARD the file FIRMWARE.DAT to install
-Insert the SD CARD in the SD slot.
-Disconnect and reconnect the power connector M1
-After powering the M1 power connector of the card, the DISP1-2 "wheel" for 8 s, and during this time,
keep the S1 button pressed until [F1] appears on the DSP1-2.
-Then press the S2 button once to confirm the update command.
-At the end of the update appears on DISP1-2 [oh
-Remove the SD CARD from the SD slot
-Disconnect and reconnect the power connector M1.

2.15 Upward working cycle
-UPWARD 1/8 - STATIONARY (DSP=1J1J or OFF)
Ready signal RDY from board to control panel during the waiting commands
-UPWARD 2/8 - STARTING REQUEST (DSP=u1J)
To activate Upward UP and High Speed HSP command input and make put on the solenoid valve ERS. The
HSP high speed command can be replaced by MSP maintenance command (P454=0) or work together to
signals MSP (P454=1), SP1 o SP2 to determine different values of high-speed set in the corresponding
parameters.
-UPWARD 3/8 - MOTOR INPUT CONSENT (DSP=u1J)
The board commutes the AVV output to give consent for motor pump starting.
In the case of non-use of this signal, the motor starting must occur after a time of about 1.5 s from the phase
2/8. In this phase, the pump oil flow is discharged in the tank at low pressure to allow a proper motor starting
and avoid hit in the cabin caused by pump direct flow to piston.
-UPWARD 4/8 - MOTOR STARTING COMPLETED AND CABIN ACCELERATION (DSP=u1)
Once finisch the motor starting (direct, star-delta or soft starter) the control must return a signal to SFY board
input. If the SFY signal is not available, it is useful to adjust the parameter P403 which sets the valve pre-
starting time, after which, however,the valve unit executes the starting phase.
The starting phase provides for the load taking, with a small movement of the cabin, and the execution of the
acceleration curve according to corresponding parameters setting: P201, P202, P203.
-UPWARD 5/8 - HIGH SPEED (DSP=u2,u6 )
The speed obtained corresponds to the parameter connected to the used high speed signal (P204 or P205,
P206, P217). In case the speed selected in the parameter corresponds to a oil flow higher than the real pump
flow rate, however the valve unit adapts its operation to the real maxim speed.

-UPWARD 6/8 - DECELERATION (DSP=u3)
Upon arrival at the deceleration contact in the shaft, turn off the high speed HSP signal and the valve unit
executes the deceleration curve seted up in the parameters P207, P208 (209,210,218) and P211 for to obtain
the low speed value corresponding to P212 parameter.
-UPWARD 7/8 - LOW SPEED (DSP=u4)
The duration of low speed phase depends on the difference between the space from the contacts of
deceleration and stopping in the shaft and the deceleration distance programmed in the parameters. When
during the deceleration and low speed phases, the parameter P 456 = 1 is setting, is calculated the distance
traveled until the stop contact that allows to run the next deceleration with a minimum low residual distance
setted in the P458 parameter. The calculation is reset when the board is off.
-UPWARD 8/8 - STOPPING (DSP=u5)
Upon arrival at the stopping contact in the shaft, it must turn off the upward UP signal. If the Soft-Stop
parameter P232 = 1, the valve unit executes the stopping curve seted up in the parameter P213.
If during the starting phase it has not used the AVV motor contact activation, to stop the motor with a delay of
1.5 s, otherwise when the signal AVV turns off, to stop the motor (and then the input signal SFY).
However not to delay the stopping of the motor more than 2 s from the arrival on the stopping contact in the
shaft.
Subsequently the shutdown of the RDY board signal also remove the ERS solenoid input. The RDY board
signal is active again after about 0.5 s, when the valve unit will be ready for the next travel.
However not to delay to remove the ERS solenoid input more than 2 s from the arrival on the stopping contact
in the shaft.

2.16 Downward working cycle
-DOWNWARD 1/7 - STATIONARY (DSP=00 or OFF)
Ready signal RDY from board to control panel during the waiting commands.
-DOWNWARD 2/7 - STARTING (DSP=d0)
To activate Downward DW and High speed HSP (or SP3 if the parameter P453=1) command input and make
put on the solenoid valves ENR and ERS. The HSP (or SP3) high speed command can be replaced by MSP
maintenance command (P454=0) or work together to signals MSP (P454=1), SP1 o SP2 to determine different
values of high-speed set in the corresponding parameters.
-DOWNWARD 3/7 - ACCELERATION (DSP=d1)
This phase provides the execution of the acceleration curve according to corresponding parameters setting:
P301, P302, P303.
-DOWNWARD 4/7 - HIGH SPEED (DSP=d2,d6)
The speed obtained corresponds to the parameter connected to the used high speed signal (P304 oppure
P305, P306, P317).
-DOWNWARD 5/7 - DECELERATION (DSP=d3)
Upon arrival at the deceleration contact in the shaft, turn off the high speed HSP signal (or the SP3 signal if
the parameter P453=1) and the valve unit executes the deceleration curve seted up in the parameters P307,
P308 (309,310,318) and P311 for to obtain the low speed value corresponding to P312 parameter.
-DOWNWARD 6/7 - LOW SPEED (DSP=d4)
The duration of low speed phase depends on the difference between the space from the contacts of
deceleration and stopping in the shaft and the deceleration distance programmed in the parameters.
When the parameter P 456 = 1, during the deceleration and low speed phases, is calculated the distance
traveled until the stop contact that allows to run the next deceleration with a minimum low residual distance
setted in the P459 parameter. The calculation is reset when the board is off.
-DOWNWARD 7/7 - STOPPING (DSP=d5)
Upon arrival at the stopping contact in the shaft, it must turned off the downward DW signal.
