When activated, the receiving unit will send a signal back, activating the relay on the transmitting unit. This allows you to connect indicator lights to show the status of whether the pump is running. You will receive two units complete with antennas and waterproof housings. Accessories such as switches, lights, contactors, pumps are not included.2 Mile Range with included Antennas. 868Mhz Licence free - no costs associated to use the system.
100mw power to meet UK Law, and can still cover two miles with the entry level included antennas. Upto 65,000 possible addresses, preset by us upon dispatch.
Authenticated communication between devices to ensure interference cannot trigger the unit. Two non voltage Inputs on each unit suitable for latching switches, or momentary switches which exceed a closed contact of 500ms when using the mimic feature. Two outputs on each unit.
Supervisory Relay, changes state if power or signal is lost on either unit. Current consumption 10mA in standby, 100mA with supervisory relay enabled. 4 x 20mm cable glands are also included but not fitted.If you would like us to fit them for you please ask! VariLink, aptly named as its variable to suit the needs of many applications, can be easily configured by yourself to act in different ways by simply changing the jumpers shown in the second picture. Here is a description of the jumpers and their functionality. SOUND: The unit beeps each time either a relay changes state, or an input changes state. If you woujld prefer the unit to be silent, then remove this green jumper. M1 & M2: These are Mimic Jumpers, for channel 1 & channel 2 respectively. For instance, with M1 on, when channel 1 receives a signal to activate its relay, it will send a signal back to the sending unit and activate it's channel 1 relay - mirroring the state of the relay in both locations. This allows you to connect visual indicators to the controller unit so that you may see the status of the device two miles away. The same applies to channel 2's jumper M2. Remove the jumper, and the signal will not be sent back to the controller unit. When removed, you can use the input terminals instead to send feedback to the controller unit. This gives you a greater level of precision so that you could connect a vibration sensor, a flow sensor, a door contact, to its input. When this sensor changes state, the signal would then be sent back to the controller unit, changing its mimic'ed relays state. LOGIC: The units have Two Dry (non voltage) inputs each.
With the logic jumper on, the unit expects a normally open switch. If you remove the jumper, the system will expect a normally closed switch.
LATCH: When this jumper is removed, the relay outputs will latch on when activated. This enables the reset screw terminals on the receiving unit. You will need to connect a push button switch to these terminals. Once pushed, the relays will reset.
DOG: Controls the Watchdog Supervisory Relay. With the jumper on, when you power on the unit the supervisory relay will change state and will remain constantly powered.
If you are running one of the units on battery power, you can reduce its current consumption from 100mA, to 30mA by removing this jumper. This prevents the relay from changing state on power up. This will however prevent you from connecting a supervisory alarm to the supervisory relay on this unit, as it will no longer change state at this location. Remember that the other unit can still have its DOG jumper on, and an alert can be connected to that unit instead, which may be powered by a transformer.
Supervisory Feature: Every 30 seconds the decies will ping each other to confirm they can still see each other. If not, the supervisory relay will change state, giving you the option to be notified of the problem. Scenarios as examples - For clarity, we will refer to one unit as the controller unit, and the other as the receiving unit. On the controller unit, we will install a float switch to monitor the level in the tank. Also on the controller unit, we will install an LED indicator to Relay 1.
On the Receiving unit, we will connect a pump to Relay 1, and leave the Mimic 1 jumper on. In Operation: The float switch changes state and the signal is sent to the receiving unit, which turns on the relay activating the pump. Once actioned, a signal is sent back to the controller unit, activating the relay to illuminate the LED Indicator.
