Tep = time between pulses Figure 5.1: Example of test pulses For the PSRW to identify the pulses as test pulses, ‘Tp’ cannot be longer than 1 millisecond, and ‘Tep’ cannot be longer than 50 milliseconds. For further information, see Chapter 8 CONNECTION EXAMPLES on page 8-1. -
Page 21: Reset
For automatic inputs, the + Vdc level must be maintained. 5.3 RESET The RST_1 and RST_2 allows the PSRW to verify an EDM (External Device Monitoring) feedback signal (series of contacts) from the external contactors, and to monitor Manual/Automatic operation. -
Page 22: Test Outputs
To monitor the digital inputs configured as contact, it is necessary to use the test outputs (TEST_A and TEST_B) generated by the PSRW. The PSRW has two test output channels that must be connected to their respective input channel (channel A to channel A/channel B to channel B) for the correct operation of the input. - Page 23 (a) Manual Rising Edge (b) Manual Falling Edge (c) Time Pulse td = Time to switch on (5 ms maximum) tm = Time to monitored reset 50 ms < tm < 3 s Figure 5.5: (a) to (c) OSSD operation PSRW | 5-5...

Page 35: Programming With Wps
Programming With WPS 9 PROGRAMMING WITH WPS The PSRW is configured using software WPS (WEG Programming Suite). This software is already used to configure other products from WEG. This software available for download on the website: www.weg.net. The WPS uses a versatile graphic interface to establish the connections between the various components, as described below. -
Page 36: Application Set Up
9.2.1 Menu When WPS is launched, a welcome screen will be displayed. There are four options on it: New configuration: Used to create a new configuration for PSRW. Open Configuration: Used to open an existing configuration save on the computer. -
Page 37: Creating A Project
When selecting the option new configuration, a popup window will be displayed asking for a configuration name (also called project name), file path and a resource name. Type these data and click on “Next”. The next step is to setup the communication. In the combo-box “Preset” on Device” area, choose PSRW among other devices. - Page 38 Programming With WPS The communication parameters are loaded automatically, by this way, no further setup are needed except the COM port if PSRW was connected to the PC (see Section 9.3 SETTING UP COMMUNICATION on page 9-7). After that, click on “Next”.
