9. SPECIAL OPTIONS
(Under Secondary)
Setting RTC
Setting the real time clock. When either the time or the date is viewed pressing ALTER will enable the user to
set the time/date.
Manifold ON/OFF
When this display is showing, pressing ALTER on the IR keyboard will toggle this selection, ON or OFF. When
off a manual option is enabled. This option allows the user to set the machine up for multiple meters and a relay
state change at a particular set points.
Manifold Autoranging Trip Points (Section 12)
Used for switching valves etc. These values are set for at what point relays open or close (usually used to
control valves).
Under the menu system the display will show SETUP AUTO pressing alter will display the following. Access by
using the
↑↓.
1
↑
2 0.0 Hz This shows the trip point in Hertz from meter 1 (Chan 1 low flow) to 2
2
↑
3 0.0 Hz This shows the trip point in Hertz from meter 2 (Chan 2. medium flow) to 3
3
↓
2 0.0 Hz This shows the trip point in Hertz from meter 3 (Chan 3. high flow) to 2
2
↓
1 0.0 Hz This shows the trip point in Hertz from meter 2 (Chan 2. medium flow) to 1
These values should not be set above or below the next meters calibration figures, leave some space for the
meter to switch over. An example is if meter 1 is set & calibrated for 20(1gpm) to 1100 hz(100gpm) and meter 2
at 100(85gpm) to 1000hz(500gpm) set trip point 1 to 2 at about 1000hz(saying 1000Hz= 92gpm) and set 2 to
1trip point at about 110hz (saying 110Hz= 90gpm) .This allows room for some variance and avoids 4050 being
in a switching loop.
The user should take care to enter a reasonable hysterisis. Refer to section 12 for the relay truth table.
Channel “ # ”
This display shows the current channel number running, however if the MANIFOLD OFF option is running then
pressing the ALTER key will change the channel number, (relay and analogue output)
VOL ON / MASS ON
Pressing ALTER (IR Keyboard) will select the VOLume or The MASS to be running. The effect is:
1. Each time the AUTO MANIFOLD changes the display will change to the new channel and display
either the VOLume or the MASS flow rate.
2. If fitted the analogue output will represent Volume or Mass flow rate.
