10.6 - DIAGNOSTICS AND SIGNALS

A few devices give out special signals that allow you to recognise the

operating status or possible malfunctions.

10.6.1 - Photocells

The photocells include LEDs that allow you to check their operational

state at any time. For led “

) see

Table 14

. For led “

” (

)

see

Table 16

TABLE 14 (PH100W)

LED “A”

Status

Action

Off

Indication with batteries inserted: the device is

not powered or is faulty

Check that the battery is inserted and with the correct polarity;

if so, check the battery's charge; if this is lower than 1V the

battery is empty. If the battery is charged then most likely the

photocell is faulty.

1 fast red flash each second

Indication resulting from insertion of the battery

or pressing the key; the device is not paired

with any system (factory condition)

Normal operation; the photocell is ready to be learned by the

CL1W.

2 fast red f pause for

1 second

Indication resulting from the insertion of the

battery or the pressure of the key; the device

is not part of a network, and the procedure for

its installation has been activated and device

is waiting to be recognised by a control unit;

this procedure is activated when you insert

the battery in the device or by pressing the

keypad; it has a duration of 10 seconds from

battery insertion or from the last press of the

button, after which it deactivates automatically

if no control unit has recognised it

Normal operation; if you want the device in question to be

added to the system, activate the device recognition procedure

on the CL1W control unit.

2 fast green f pause

for 1 second

Indication following battery insertion when the

automation is stopped; the device is paired

with a system and is communicating correctly

with the control unit

Normal operation

1 fast green flash followed by

1 fast red flash + 1 second

pause

Indication following battery insertion when the

automation is stopped; the device is paired

with a system but the control unit does not

communicate (could be switched off)

Check that the automation is actually stopped, that there is no

testing procedure in progress, and that it is powered and not in

stand-by; if the previous tests are positive check the quality of

the radio signal received from the device

1 flash per second, green on

the transmitter

The automation is moving or in test

Normal operation; if the indicator colour is red, see the note (*)

1 slow flash per second,

green on the receiver

The automation is moving or in test and the

device is receiving an optimum infrared signal

level

Normal operation; if the indicator colour is red, see the note (*)

1 slow green flash, on receiver

(**)

The automation is moving or in test and the

device is receiving a good infrared signal level

Normal operation; if the indicator colour is red, see the note (*)

1 fast green flash, on receiver

(**)

The automation is moving or in test and the

device is receiving a poor infrared signal level

Normal operation but check the TX-RX alignment and that the

glasses are properly cleaned; if the indicator colour is red, see

note (*)

1 very quick flash, green on

the receiver

The automation is moving or in test and the

device is receiving a bad infrared signal level

If normal operation is limited, check the TX-RX alignment and

that the glasses are properly cleaned; if the indicator colour is

red, see note (*)

Green led steady on

The RX is receiving no signal

Check for any obstruction between TX and RX. Check that

the LED on TX is flashing slowly. Check the TX-RX alignment

If normal operation is limited, check the TX-RX alignment and

that the glasses are properly cleaned; if the indicator colour is

red, see note (*)

(*) Note - If the indicator colour is red, one of the following problems may be identified: 1) The maximum number of daily manoeuvres has been
exceeded for a long period. - 2) The battery is old and should be replaced. - 3) The solar cell used as a solar charger is damaged. - 4) The device
does not receive sunlight and consequently cannot charge the battery.

If the battery is fully charged the led colour is green; otherwise it is red

(**) Note - There are 10 flashing frequencies which indicate the IR signal reception power
