SUPERtrol II Flow Computer

Define the flow quantity per output pulse if the relay is configured
for "RELAY PULSE OUTPUT".. This is expressed in units per pulse
(i.e. ft
3
/ pulse).
Note:
Ensure that the max. flowrate (full scale value) and the
pulse value entered here agree with one another. The max.
possible output frequency is 5Hz. The appropriate pulse
value can be determined as follows:
Pulse value > estimated max. flowrate (full scale)/sec
required max. output frequency
Input:
Number with floating decimal point: 0.001...1000.0
Display:
1.000 ft3/P
PULSE VALUE
Enter the pulse width. Two cases are possible:
Case A: Relay set for "MALFUNCTION" or limit value
The response of the relay during alarm status is determined by
selecting the pulse width.
• Pulse width = 0.0 s (Normal setting)
Relay is latched during alarm conditions.
• Pulse width = 0.1...9.9 s (special setting)
Relay will energize for selected duration, independent of
the cause of the alarm. This setting is only used in special
cases (i.e. for activating signal horns).
Case B: Relay set for "RELAY PULSE OUTPUT"
Set the pulse width required for the external device. The value
entered here can be made to agree with the actual flow amount and
pulse value by using the following:
Pulse width < 1 .
2 • max. output frequency (Hz)
Input:
Number with floating decimal point:
0.01...9.99 s (pulse output)
0.00...9.99 s (all other configurations)
