WIRELESS 4-20mA TRANSMITTER OPERATING MANUAL

• LED does a single green flash – failed to send

The button wakes the sensor up, and the first green flash is seen. After the settling time

and reading of the mA value, it sends the data to the IWR Receiver. The data send failed,

so there was no second flash. It will now sleep for the sleep time, then wake and repeat

this process.

• LED does one or two long red flashes followed by six short red flashes –

successful join to network

When the IWTxT is first switched it tried to join a network and was successful. It will now

sleep for the update rate time, then wake, read the input, and send the data to the IWR

Receiver.

• One or two long red flashes – failed to join the network

When the IWTxT is first switched on it tried to join a network but in this case, it was

unsuccessful. The IWTxT will now sleep for eight hours to conserve battery life before

waking up and trying to join again. The push button can be used to wake it up to force it

to try and join a network again.

5. Push button use

If the push button is pushed and released quickly the sensor is woken from sleep to read

the mA value. The led will flash green once or twice as described above.

If the push button is pushed and held for 5 seconds the Z-Head can be forced to leave

the network, it was joined to. It will then try and join again, indicated by long then short

red flashes as described earlier. This action may be required if routers are used in the

network.

Possible Causes

Unit not switched on, switch on using SW2.

The battery is not installed correctly.

The battery needs replacing.

IWR receiver not switched on.

IWR receiver is not set up for the same RF

network.

IWR receiver not within range of the

transmitter.

If an IWR-1 receiver is used, ensure that

the transmitter is set to Tx Channel 1

IWR receiver set up incorrectly, see IWR

user manual for further details.

Check that the green external LED on the

receiver is flashing when the transmitter

push button is pressed as the receiver may

be out of range.
