## **LED indication** 

The Green LED (Output) is a dual purpose indicator. When 24V power is applied the Green LED is dimly lit. When the output thyristors are activated, the Green LED is lit up more brightly in tandem with application of power to the load. 

The Yellow LED (Data) shows when there are communication communication activity. It errors or when the relay is lights up for the period of time operating abnormally. In the that the relay is involved in case of communication errors, communication over the the Alarm LED is reset by the RS485 bus. This applies for next valid communication seqboth transmission and recepuence. When there is abnortion. mal operation the Alarm LED The Red LED (Alarm) lights up resets when the operating con- 

ditions revert back to normal. All three LEDs flashing continuously indicate that the device is in configuration mode (Modbus address set to unsopported value). Details shown in product manual.

Notes: 

1. A terminating resistor (value 100 Ω to 130 Ω ) must be fitted at each end of the RS485 network. 

2. 24V power may be applied through terminals 6A4, 4A2 or through the RJ-45 connector. If daisy chaining several devices using standard ethernet patch leads, the connection to 6A4, 4A2 is optional for the second and successive devices. For large networks it is necessary to connect 6A4, 4A2 every 25th device. 

3. Max. no of daisy chained devices may be limited by patch-lead conductor diameter and length. 

4. Refer to product handbook for detailed installation instructions. 

## **O eration p** 

**Mode 0 – ON/OFF control** In Mode 0 the relay operates as a standard ON/OFF relay with zero switching. In this mode the relay can deliver either 0% or 100% power. This mode is ideal for systems where the process controller employs a digital process variable, similar to that used in standard solid state relay applications. 

**Mode 1 – Phase angle control Mode 2 – Distributed firing** In Mode 1 the load power is In Mode 2 full cycles are adjusted by delaying the thyrisswitched ON/OFF over a peritor switching signal according od of 256 mains cycles. The to the required power. The number of cycles that are resulting output is a chopped switched ON corresponds to sine-wave. The relay switches the value specified in the load itself off every half cycle. power register. This mode Timings are calculated such uses an algorithm that distribthat a linear power response utes the ON cycles evenly over curve is obtained. This mode the 256 cycle period. is suited for loads where continuous control of power is required. 

**Mode 3 – Burst firing** 

In Mode 3 full cycles are switched ON/OFF over a period of mains cycles as defined by the Time-Base Register. Mode 3 uses an algorithm that will switch ON a number of cycles in a continuous burst for a time period corresponding to the required power.
