  • Page 6: Overview

    505U message. The 505U transmits the input message to a 105U module, which sets an output signal to be the same value as the 505U input, or the 105U passes the input message to another device (PC or PLC) via its serial port.

  • Page 7: Power Supply

    The power consumption of the 505U is very small as it conserves power by reverting to “sleep” mode between transmissions. The 505U can be powered from an external 12V DC supply, or a 3.5 – 5V battery supply. The battery supply can be either internal AA alkaline or lithium batteries, or an external battery pack.

  • Page 8: Configuration

    Each module must be configured before it can be used. Configuration is performed using a PC (or a laptop computer) connected to the module via the internal RS232 port on the 505U. 505U configuration software is required and is provided with each order.

  • Page 9: Operation

    (on to off, or off to on), or every 0.5 seconds to check if a timed update transmission is due to be sent. Normal operation of the 505U is indicated by a brief flicker of the OK LED light on the front panel approximately every 10 seconds.

  • Page 10: Digital Inputs

    A digital input can be an external digital input or an internal status input (setpoint status or low battery alarm). The 505U will transmit the value of the digital input whenever it changes from off to on or from on to off. A paralysis time may be configured to prevent another transmission within this time. The 505U will also transmit an update message if a message has not been transmitted for that input within an “update time”.

  • Page 11: Analogue Inputs

    The analogue input uses a “sample time” and “warm-up time” configured by the user. The sample time (1 minute to 20 days) “wakes” the 505U from sleep mode and turns on the analogue loop supply. The “warm-up time” (0.5 – 127.5 seconds) allows the transducer to reach rated accuracy before the 505U makes a measurement of the analogue signal.
  • Page 12 0.25% to 100% (0.05mA to 20mA) with a default value of 3% (0.6mA). If the change in the signal since the last transmitted value is less than the sensitivity, then the 505U will not transmit the analogue value.

  • Page 13: Setpoint Status

    For example, if you wish to have a failure alarm within 10 minutes of a system failure, set the output reset time at the 105U to 10 minutes and the update time at the 505U to 4.5 minutes.

  • Page 14: How To Design A Remote Monitoring System

    How to Design a Remote Monitoring System 2.4.1 Achieving reliable radio transmission A system can theoretically have an unlimited number of 505U modules, but in practice, the number is limited by the amount of radio traffic on one frequency in the system. When a radio channel becomes unreliable because of radio traffic, then a second radio channel must be used to increase the size of the system.

  • Page 15: How Far Will The Radio Transmit

    • Maximum radio transmitter power allowed in the country The transmitter power level of each 505U is set in the factory to the maximum power allowed in the country of sale. The maximum output power of the 505U is 500mW, however only 250mW can be achieved using internal batteries.

  • Page 18 Note that battery life is shortened during configuration or diagnostics. When the serial cable is connected to the 505U, the module does not revert to sleep mode and the power consumption is considerably increased. These periods should be minimised if you are using a battery pack.

  • Page 19: Hardware Installation

    110/220/240V mains power must NOT be connected to any input terminal of the 505U module! The 505U module is housed in a weatherproof enclosure with external power and input signals connected via a weatherproof connector at the bottom of the module.

  • Page 20: How To Mount The 505U

    505U Radio Telemetry Module 3.1 How to mount the 505U The 505U module is housed in an IP66 weatherproof aluminium enclosure. To mount the 505U, remove the four screws in the top plate, and carefully remove the cover. The two mounting holes should now be visible.
  • Page 21 Whip antenna A whip antenna is a small rubber coated antenna designed to connect directly to the 505U BNC connector. It is suitable for applications up to 25% of the maximum distance for the power level.
  • Page 22 OBSTRUCTIONS INSTALL MORE THAN ON STAKE The 505U can produce 500mW of radio power when an external 12VDC supply is used, but only 250mW of power with internal batteries. This power may be boosted to 500mW by using a higher gain antenna (3dB) such as a 3 element Yagi or a 3dB collinear antenna.
  • Page 23 (horizontally polarised). For a two station installation, with both modules using YAGI antennas, horizontal polarisation is recommended. If there are more than two 505U modules transmitting to a common 105U module, then the YAGI antennas should have vertical polarisation, and the 105U module should have a dipole or collinear (non-directional) antenna.

  • Page 26: Power Supply Installation

    Power Supply Installation 3.4.1 External Power The 505U module will accept an external supply of 11.5 - 15.0 volts DC. An external supply with a battery and battery charger is suitable. Negatively grounded or floating supplies are acceptable, however positively grounded supplies must not be connected. The 505U connects the negative supply (COMMON) to “ground”.
  • Page 27 The BU-5-1 can be installed underneath the 505U or beside it. The BU-5-1 uses the same type of enclosure as the 505U and is mounted in the same way. The BU-5-1 has a “cable tail” which plugs into the 505U. The input wiring is then connected to a socket on the BU-5-1.

  • Page 28: Input Signal Connections

    Inputs can be voltage free contact or open-collector transistor Inputs do not have any surge protection. If the sensor or switch is mounted a long way from the 505U module, external isolation such as a relay may be required for surge protection. Page 28...

  • Page 29: Shaft Encoder Connections

    EXT POWERED TRANSDUCER Loop powered transducers must be suitable for low voltage operation. Loop voltage available for the transducer is 8.5V for 505U-B modules and 1.5V less than the power supply voltage for 505U- E modules. Shielded cable is recommended for analogue input loops to minimise induced noise and radio frequency interference (RFI).
  • Page 30 Not Used. Not Used. The DTR signal must be connected to the 505U to enable communications and “wake up” the microprocessor. This means that the DTR wire must be connected - the PC does not need to control DTR. When communications is established, the green LED will light continuously.

  • Page 31: Configuration

    Select “505-2” as the unit type for 505U modules. Each 505U has a unit address and a secondary address. Up to eight 505U modules can use the same system address. If you enter the same unit address for more than one 505U, the configuration software will automatically increase the secondary address.

  • Page 32: I/O Mapping

    The setpoint status of the 505U is mapped (inverted) to DO3 of 105U#14, using 105U#13 as a repeater. The 505U AI is also mapped to AO1 of this module. That is, the AI is mapped twice. The mapping configuration for the 505U would be : 4.2 Update Transmission Times...

  • Page 33: Digital Inputs

  • Page 34: Analog Setpoints

    If both the sample time and warmup time are set to zero, then an analogue measurement will be taken on every 505U cycle (every 0.5 sec). 4.5 Analog Setpoints A high setpoint value and a low setpoint value may be entered.

  • Page 35: Pulse Inputs

    User Manual The setpoint values may be set between 0 and 100% corresponding to 0mA and 20mA. The low setpoint may be set to the same value high setpoint, however the low setpoint should not be set to a higher value than the high setpoint.

    LED extinguishes a sleepmode state is indicated conserving the 505U's battery power. If the OK LED does not flash, a flat battery condition or an internal failure may exist. If the 505U module is located outside, then it will be difficult to see when the LED indicators are on. Remove the front lid of the 505U to see the LED's better.
  • Page 39 The configuration software provides some diagnostic features to help identify problems. To use these features, connect the 505U to a PC using a RS232 cable and run the configuration software. The OK LED will light continuously once the module is in configuration mode.
  • Page 40 This feature turns the radio transmitter on continuously for radio path testing. A series of 1 and 0 data bits is transmitted. This feature is not recommended for 505U-B versions as it will significantly reduce the life of the batteries.
