w To set the relays:
1. From the Main menu press 2. The 2.0 PORT SETUP menu title will appear.
2. Press 2, the Relay Setup option.
3. Press 1 or 2, corresponding to the relay to be set.
4. After entering the user password (if it is enabled), press 1, Unit, to select the
switching parameter. Press 1 to switch on flow rate or press 2 to switch on
temperature. (The current selection is shown in parenthesis to the left of the question
mark.)
5. Press 2, Activate On, to select the switching scheme desired (See Figure 13). Press
1 for an Above, press 2 for Below, press 3 for Inside or press 4 for Outside.
Depending on the choice made, enter 1 or 2 switch point values. For example, if
Inside has been chosen, the user will then be prompted to enter a low range switch
point and a high range switch point. The values entered must be within the displayed
allowable range.
6. Press 3 to change the switch delay. Delay pauses the change in relay state when a
switch point is crossed. The value entered is approximately equal to seconds.
7. Press 4 to change the dead band or hysteresis of the switch point (See Figure 13). The
dead band or hysteresis has a value of flow rate or temperature depending on whether
switch on changes in flow rate or temperature have been chosen.
8. Press 5 to save and exit to the previous menu level. Press Y when asked to save
permanently.
From the keypad, the relay state can be switched. This can be used to test the interface with
relays. This is also described in Chapter 5 Troubleshooting.
w To test the relays:
1. From the Main menu press 2. The 2.0 PORT SETUP menu title will appear.
2. Press 2, the Relay Setup option.
3. Press 3, for the Test Relays option.
4. Pressing 1 or 2 will toggle the states of the respective relays. The present state of the
relays are displayed in parenthesis.
The functions within menu level 5.0 provides a quick means of displaying the current
system parameters for the flowmeter. The flow rate and temperature units of measure, the
state of the analog outputs and relays or other critical information can be viewed from this
menu.
w To view the flow range, the flow rate units of measure and the area:
1. From the Main menu press 5. The 5.0 VERIFY menu title will appear.
2. Press 2, the Flow option. The sequence of information will be displayed to the screen
as shown in Figure 14. Press Enter twice to proceed. The first line of screen 1 is the
window title. Line 2, the Flow Factor is the conversion factor from the internal units
of measure (SF/S) to the desired units. Lines 3 and 4 show the flow range and the
current flow units. Screen 2 shows the standard density of the flow stream.
3. Press 4, the Area option. Screen 3, shown in Figure 14 will appear. The second line
shows the pipe area and units. The third line is the inside diameter of the pipe. (The
third line will appear only if the pipe I.D. is entered. If Std Velocity flow units are
used the Area option is not available.)
