Resumen del manual
Use the [^] or [Ў] keys to select the correct alarm relay action for the application, Latch, Sentry or Non-Latch. Selecting “Sentry” enables the Sentry controller to make all alarm action decisions. * indicates the current selection. • Gas Factor: A calibration standard of Methane may be used in conjunction with scaling factors to cause alarm function in %LEL scale of another gas. See Appendix I for a list of the scaling factors. Note that if the 5100-02-IT is interfaced to a Sentry controller that the gas factor can be set in the Sentry or the Gas Sensor Module but NOT IN BOTH. It is recommended that the gas factor be adjusted in the Gas Sensor Module so that the display values on both the Gas Sensor Module and the Sentry are matched. Note that gas factors are not applicable during calibration. • 4-20mA: Use the [^] or [Ў] keys to select Calib, or CalibOut TblOut menu and press [E]. The “Calib” section of the menu allows the user to calibrate the 4 mA and 20 mA outputs. To calibrate the 4 mA and 20 mA outputs it is necessary to have an amp meter connected to the 5100-02-IT and upon selecting the 4 mA output calibration then the [^] or [Ў] keys can be used to adjust the 4 mA reading on the amp meter until it reads 4 mA. Similar steps can then be performed for the 20 mA output. The CalibOut section allows the user to select the 4-20 mA output action desired during calibration. * indicates the current selected value. Available selections include: • Track – the 4-20mA value tracks the calibration gas exposed to the gas sensor module • C2.5mA – the 4-20mA value is held at 2.5mA during calibration • C4.00mA – the 4-20mA value is held at 4.0mA during calibration. The Tbl Out menu enables the user to select the mA output value for the Trouble Alarm. Select “T1.5mA” to choose the 1.5mA default valve. Or select “User mA” and use the [^] or [Ў] keys to select any valve between 0.5mA and 3.7mA. • RS-485 - Use the [^] or [Ў] keys to select Address or Baud rate menu and press [E]. Note that the 5100-02-IT has a rotary switch on the faceplate and it is used to select addresses 1-15. When connected to Sentry the user can select 1-8 and using Modbus RS-485 the user can select addresses 1-15. For Modbus addresses above 15, set the rotary switch to 0 and then use the “Address” menu to select any address between 16 and 254. The Baud rate menu allows the user to select a baud rate of 38400, 19200, 9600, 4800 or 2400. * indicates current selection. RS485 default parameters are: 38,400 baud, 8 bits, 1 stop bit, no parity Page: 20 Model 5100-02-IT Combustible Gas Sensor Module Function Display Description Key Reference --0%LEL-Default Display ME Mode ALMRSET: Mode Function - Alarm Reset .• ME Mode CALIB:-Mode Function - Calibrate .• ME Mode SETUP:--Mode Function - Set Point Adjustments .• ME Enter Alarms S.P.
