USER INSTRUCTIONS

General description

The programmer is used for the timed management of a load, with programming on a daily and weekly basis using a relay output.

The programmer is fitted with a backlighted LCD visual display unit (VDU) and four control buttons for managing the device.

USER INSTRUCTIONS

Operating mode

The programmer provides three different operating modes:

• MANUAL
• AUTOMATIC
• OFF

The MODE key is used to switch from one mode to another.

In manual mode it is possible to set the output in a permanent state. The time, the day of the week, the message MAN and the indication of the relay status (ON/OFF) are displayed on the VDU.

In automatic mode the device uses a program set by the user, which can also be differentiated for each day of the week. The time, the day of the week, the message AUTO and the current relay status (ON/OFF) are displayed on the VDU. The message AM or PM shows which fraction of the day is displayed in the hourly profile.

The segment relative to the current time blinks in the hourly profile with the representation of the status of the output (high segment ON, low segment OFF).

In OFF mode the N.A. relay contact is kept constantly open while the N.C. contact is closed.

The time, the day of the week and the message and indication of the relay status (OFF) are displayed on the VDU.

Setting parameters

The SET/PROG key is pressed once to set the parameters.

The message SET is displayed on the VDU.

At this point the following can be modified, in sequence:

• the day of the week
  the hour
• the minutes

The value of each parameter is confirmed by pressing the MODE key.

The setting phase is exited by pressing the SET key again or, in automatic mode, 30 seconds after the last key entry.

Setting the day of the week

When the day of the week bar blinks, select the day of the week using the keys(Monday=1, Tuesday=2....

Sunday=7).

The value set is confirmed by pressing the MODE key within 30 seconds.

Setting the hour

When the hour figures blink, set the hour using the AV keys.

The values set are confirmed by pressing the MODE key within 30 seconds.

Setting the minutes

When the minutes figures blink, set the minutes using the key.

The values set are confirmed by pressing the MODE key within 30 seconds.

USER INSTRUCTIONS

Programming

The SET/PROG key is pressed twice to personalise the preset daily/weekly program or to make a modification to a previously set cycle.

a) The message PROG is displayed on the VDU while the bar for the first day of the week starts to blink.

The required day is selected with the keys

The selection is confirmed by pressing the MODE key within 30 seconds.

b) The profile of the day selected is displayed on the VDU.
c) The time starts to blink.

The keys are used to select the start hour from which it is required to modify the proposed profile; while the time profile is being incremented, the column relative to the selected time will blink. The selection is confirmed by pressing the MODE key within 30 seconds.

The message ON (or OFF) blinks on the VDU.

The Key can be used to modify the output status, The modification takes effect starting from the time selected and extends until the next transition or until the end of the day that is being programmed if there are no subsequent transitions.

The choice is confirmed by pressing the MODE key within 30 seconds.

USER INSTRUCTIONS

Programming

e) The time blinks, select the start hour from which it is required to select a new switch as described in point c).

The time is incremented/decremented in steps of 5 minutes each time the keys are pressed.

It is therefore possible to define up to 12 relay switches every hour.

The programming is confirmed by prolonged pressure on the MODE key.

A move is made automatically to programming the next day.

The programming phase is exited by pressing the SET key or, in automatic mode, 30 seconds after the last key entry.

Save and propose again

If, however, it is required to copy the program directly to the next day, the programming just done is confirmed by pressing the keys simultaneously 30 seconds.

In this mode the program just run is saved and also proposed again the next day; to copy and save the same program over several days, repeat the operation of simultaneously pressing the key within 30 seconds.

On completion of weekly programming the SET/PROG key is pressed to return to normal operating.

Automatic operation

The program is started by selecting automatic mode by pressing the MODE key until the AUTO symbol is displayed on the VDU.

In AUTO operating mode the hourly profile relative to the fraction of the day in progress (AP/PM) is displayed.

The profile relative to the other fraction of the day can be displayed by pressing the

keys simultaneously. The indication is active for 5 seconds, after which the current profile reappears.

Manual operation

The manual operating mode activated by pressing the MODE key until the MAN message is displayed on the VDU.

The Kays are used to set the required output status. The selected status (ON/OFF) is displayed on the VDU.

Visual display unit

The LCD visual display unit is provided with backlighting which is active for 5 secs whenever a key is pressed.

In SET or PROG mode the backlighting remains active during parameter setting and programming. It is deactivated on exit from these modes.

Remote control

The programmer can be connected to the GW90821 GSM remote control unit using a serial connection. SMS commands (e.g. from a cellular telephone) can be used to:

• Set the operating mode (MAN/AUTO/OFF)
• Set the output status (ON/OFF)
• Request the current status

Each command SMS sent to the device will be answered by a corresponding SMS in confirmation (with non-configurable predefined text); the status request message provides a reply including the following information:

• current operating mode (OFF/AUTO/MAN)
• output status (ON/OFF)

Whenever the output status or operating mode are modified from the remote control unit, the symbol is displayed on the VDU.

The symbol also appears for the current contact status request.

The symbol remains displayed on the VDU until a key is pressed.

Operating in case of blackout

The device is fitted with a backup battery that guarantees updating of the time and day of the week in case of blackout.

When power is supplied by the battery alone there is an autonomy of 24 hours in the following conditions:

time display active
- backlighting inactive
- output status display inactive
- relay switching not enabled (the relay contact retains the status prior to the blackout)
- front keys inactive (except when all 4 keys are pressed simultaneously)

In the absence of power, simultaneously pressing all four front keys causes disconnection of the backup battery inside the device.

This function is used to preserve the efficiency of the battery when the device is not used for a long period.

The battery is connected again automatically once the device has been connected to the power mains.

The set programs are not lost either in the case of a blackout or in that of battery disconnection.
