Use the DELETE command to clear all data files. Use the UNDELETE command to recover the deleted data. NOTE The UNDELETE command only recovers the part of the deleted data that has not been recorded over yet. Operating Relays Quantity for Relay Output A relay monitors the quantity chosen for the relay output.
USER'S GUIDE____________________________________________________________________ 1102-007 Figure 39 Relay Output Modes Mode 4 is usually used if an alarm needs to be triggered when the measured value exceeds a safe range. The relay is active when measurement is in range, and is released if the value goes out of range or a power outage occurs. NOTE If the measurement of the selected quantity fails or the barometer loses its power, the relay is released.
Chapter 4 ________________________________________________________________ Operation Hysteresis The hysteresis function prevents the relay switching back and forth when the measured value is near to the setpoint values. The relay is activated when the measured value passes the exact value of the setpoint. When returning to and passing through the setpoint again, the relay is not released before the value reaches the setpoint increased/decreased by the hysteresis value, see Figure 39 on page 94.
USER'S GUIDE____________________________________________________________________ FAULT STATUS relay is usually used in conjunction with an analog output to obtain validity information for the output value. NOTE If a barometer loses its power, all status-based relays are released similarly to the case of an instrument failure. Enabling/Disabling Relays You can deactivate the relay outputs for example for service purposes of your system.
Chapter 4 ________________________________________________________________ Operation Example of normal limit switch: Selecting relay 1 to follow pressure measurement and relay 2 to follow measurement of pressure from barometer module 1. One setpoint is chosen for both outputs. >rsel P P1 Rel1 P below: Rel1 P above: Rel1 P hyst : Rel1 P enabl: Rel1 P1 below: Rel1 P1 above: Rel1 P1 hyst : Rel1 P1 enabl: > 980.00 hPa ? 995.00 hPa ? 1020 0.10 hPa ? 1 ON ?

USER'S GUIDE____________________________________________________________________ Testing the Operation of Relays If a relay module is installed on PTB330, you can use either the optional display and menus or the serial line command RTEST to test the operation of relays. For testing via menus see section Testing the Operation of Relays on page 61. Testing activates relays even if they are disabled. Use the module push buttons to activate the relays.
Chapter 4 ________________________________________________________________ Operation Operating RS-485 Module RS-485 interface enables communication between RS-485 network and the barometer. The RS-485 interface is isolated and offers a maximum communications rate of 115 200 bits/s. (For maximum bus length of 1 km, use bit rate 19200 b/s or less.) When selecting an RS-232-RS-485 converters for the network, avoid self-powered converters as they don't necessarily support the needed power consumption.
USER'S GUIDE____________________________________________________________________ ADDR Addresses are required only for POLL mode (see serial line command SMODE on page 85). Use the ADDR command to input the RS-485 barometer address. ADDR [aa] where: aa = address (0 ... 255) (default = 0) Example: the barometer is configured to address 99. >ADDR Address : 2 ? > 99 SDELAY With the SDELAY command you can set delay (response time) for the user port (RS232 or RS485), or view currently set delay value.
