For example if the input pulse rate is 7 pulses per m of gas then a divider of 7 will result in a pulse count corresponding to the number of m Note that the divider must be an integer gt The divider could be used to slow down the pulse rate If the input pulse rate is 5KHz then the base 16 bit counter will overflow in approx 13 seconds If the overflow counter is not used then this may be too fast to be processed by HMI software If a divider of 100 is used then the counter will take over 20 minutes to overflow There is no divider for PII If the pulse count is transmitted to a pulse output on a 105U module the 105U will compare the input count to its own output count the count of output pulses and will then output pulses until the two counts are the same If the pulse counts are transmitted to a 105U C or 105U G interface module then the 105U C will store the pulse count value in an internal register For pulse rates higher than 10 Hz the Fast Pulsed Inputs option should be selected This increases power consumption of the module significantly and is not suitable for a battery power supply Overview e Pulse inputs are counted as 2 x 16 bit registers e Pulse count is transmitted when the count has increased by the sensitivity amount since the last transmission e Update message if the input value has not been transmitted within the update time 10 Manual 505K_1 3 Page 11 505U K Radio Telemetry Module seco

17. above comments you need to consider the affect of re transmissions on other messages being transmitted from the same 505K module Once a 505K starts transmitting a message all transmissions for this message must be complete before another transmission can start The time between retransmissions of the same message 1s a random time between 0 5 and 4 seconds For example if a module is configured to transmit each message 5 times then each message will take up to 16 seconds Another message cannot be transmitted until the previous message has finished In the above example the maximum number of messages which can be transmitted reliably is approx 4 per minute If more messages are required then a lower number of re transmissions should be selected 2 5 2 How far will the radio transmit The 505K will operate reliably over approx 5km line of sight The distance that can be reliably achieved will vary with each application and is dependent on the following factors e Type and location of antennas the higher an antenna is the further it will transmit e Amount of radio interference from other transmitters or radio noise e Obstructions such as buildings hills or trees in the radio path Manual 505K_1 3 Page 17 505U K Radio Telemetry Module 2 6 Calculating Power Consumption The following information may be used for calculating power consumption Voltage Supply BU 5 2 Battery A volts a 30 E constant regardless of voltage 3 4
