- Page 3 User Manual WARNING For 505K modules, a radio licence is not required in most countries, provided the module is installed using the antenna and equipment configuration permitted. Check with your local 505U distributor for further information on regulations. For 505U modules, operation is authorised by the radio frequency regulatory authority in your country on a non-protection basis.

User Manual Analogue continuously variable signals (0-20mA, 4-20mA, 0-10mA, 0-10V) Examples: measured tank level, measured process temperature Some internal signals may also be transmitted to outputs in the network: • Setpoint Status (digital signal set or reset depending upon the value of the analogue signal compared to a high and a low setpoint value configured in the 505K) •... - Page 8 505U-K Radio Telemetry Module 505K configuration software is required and is provided with each order. Configuring a module requires the entering of “input mappings” and setting operating parameters for each input. An “input mapping” links an input signal to an output channel at a remote module (or a “destination address”).

Page 9: Operation
User Manual 2 OPERATION 2.1 Normal Operation Once configured using the 505K configuration software, the 505K module will normally be in “sleep” mode to conserve power. During sleep mode, the microprocessor controller powers down, and the analogue loop supply is turned off. The microprocessor will automatically “wake up”... -
Page 10: Inputs
505U-K Radio Telemetry Module this. Depending on the type of input signal (digital, pulse or analogue), the 505K must determine what type of signal change is required to send a transmission: 2.4 Inputs 2.4.1 Digital Inputs A digital input can be an external digital input or an internal status input (setpoint status or low voltage alarm). - Page 11 User Manual count. In addition, an update transmission of the pulse count will be transmitted if the pulse count has not been transmitted for the update time. If an update time of zero is selected, then no update messages will be sent. The maximum pulse input is: 300Hz for contact or NPN inputs (1 msec minimum on-time and off-time), or 10KHz (30 µsec minimum on-time and off-time) for TTL inputs.

505U-K Radio Telemetry Module • After each transmission, another transmission for that input is disabled for the paralysis time (0 – 127.5 sec). • PI2 can be scaled by a configurable divider. The diagnostics functions of the 505K allow the user to manually set the counter values to any value (refer section 5 of this manual). -
Page 13: Analogue Inputs
User Manual pulse inputs are used, then 0% analogue signal will correspond to zero pulse rate (0Hz). The pulse rates are treated as analogue inputs and follow the rules for an analogue input as described below. 2.4.5 Analogue Inputs The analogue input can measure from 0 – 24mA or 0 – 10VDC. Current or voltage input can be selected by an internal selector (refer Installation section of this manual). -

505U-K Radio Telemetry Module to sleep mode. The loop voltage available for a transducer is approx. 24VDC. If the warm-up time is set to the same or more than the sample time, then the analogue loop will be on continuously, and the 505K will measure the signal based on the sample time. For example, if the sample time is 10 seconds, and the warm-up time 20 seconds, then the analogue loop will be continuously active and a measurement made every 10 secs. -

User Manual the cable loss. For example, a 3 element Yagi with 10 metres of Cellfoil cable has a net gain of 2dB (5dB – 3dB). Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses. -

Page 35: Analogue Input
User Manual A paralysis time is useful in large systems when a lot of inputs can change at the same time. Once a 505K has transmitted a message, it cannot transmit another message during the paralysis time - this is to prevent overcrowding of the radio channel. An example could be a system monitoring environmental alarms. -
