Sensors Use the pull-downs to select which type of sensor is connected to that input. Connection Problems Link to Analog Inputs page does not appear The controller not detecting an analog input board at power up causes this problem. It will take some experience to find out what the normal output on-time will be. Possible Causes Corrective Actions The system has experienced too high a rate Evaluate system The rate high alarm point is too low Go to the input page and reset the limit You are getting false contacts. This should be less than the normal bleed set point. To activate a software feature in the field, purchase the activation key file from your distributor and save it on the root drive of a USB flash drive.

To use this feature, you will need to complete the fields for: Most U3 smart drives come with an uninstall utility that converts the U3 smart drive into a regular USB flash drive.
Page Relay Control Mode Click on the arrow of the pull down menu and select the way that you want to control the relay. What are the minimum requirement for my PC? Press the Enter key to continue. How does my WebMaster benefit from it? Flow Meter should be selected if an analog flow transmitter is connected to that input.
Page Temperature Walche, Error This error message is caused by the temperature signal being outside the normal range aroundohms for contacting conductivity sensors, 15, tofor electrodeless conductivity sensors, to ohms for pH sensors and high temperature conductivity sensors.
Refer to the example below under Proportional Band.
Maximum total loop resistance ohms. If you do perform the upgrade, the WebMaster suspends it functions until the upgrade is complete. Refer to drawing for exact location. Even the modem and Ethernet walcem are plug-ins.
Select the relay to be interlocked when the switch connected to the DI is the in the state for the relay to be off. Superior check valve design wil guarantee fast priming and reliable performance. Page 46 Chlorine or Chlorine Dioxide Calibration 1 pt Process Cal Ensure that the sensor is conditioned and equilibrated to the temperature of the sample.
What types of flowmeters can I use? Custom Message for Open Contact You may specify a custom message to be displayed in the System Summary when the digital input contact is open.

Page Logging Interval Type in the text box the time required between data points. The controller will display a calibration failure if the offset calculated in the Zero Calibration is outside of the range —20 to 40 mV or the slope calculated in the One Point Process Calibration is outside of the range to mV per ppm.
Once this information is entered, a remote PC may be used to configuring all or the set points that are unavailable with the keypad. Front Panel Display Turn the power switch on.
If Not Used is submitted, a field will appear for entering the makeup conductivity manually. It is our goal to continually provide our customers with the best possible equipment, technology, and service.
Select the method you would like to use. The new value will be displayed.

The following sequence occurs while sampling: If successful, press the Enter key after the sensor wwlchem been replaced into the sample stream to resume control. It can also be equipped with eight 8 analog inputs and twelve 12 digital inputs capable of monitoring tank levels, providing interlocks, feed verification and receiving other plant parameter signals such as steam load, phosphate concentration, etc. Page regardless of the set points by selecting Hand, or force the relay open regardless of the set points by webmmaster Off.
For point level devices, which do not use a mA signal, wire wegmaster and program with the Digital Inputs section. You should measure 25 ohms resistance, otherwise this input is not good.
Everything you need resides on the WebMaster itself. A sensor of this type must be connected to digital input A, B, C or Some models allow you to change set ewbmaster but not change the control mode. No, each controller needs to send data to VTouch as independent controllers.
Possible Causes Corrective Actions The temperature sensor is not connected.
