Display
Selects the type of pressure switch connected to the "Low City Pressure"
digital input (H1-0x = 73).
0: Normally Open (closed indicates the "Low City Pressure"
condition)
1: Normally Closed (open indicates the "Low City Pressure"
condition)
Sets the amount of time a "Low City Pressure" condition must be present
before the drives will stop. Also sets the amount of time that the pressure
must be adequate before the drive system will re-start.
Sets the amount of time the drive's output will be delayed and the Lube
Pump digital output (H2-0x = 55) will be energized.
A setting of zero will disable this feature.
Selects the type of pressure switch connected to the "Remote Drv Disbl"
digital input (H1-0 =72).
0: Normally Open (closed indicates the "Remote Drive Disable"
condition).
1: Normally Closed (open indicates the "Remote Drive Disable"
condition).
Sets the amount of time a "Remote Drive Disable" condition must be
present before the drive will stop.
Sets the amount of time a "Remote Drive Disable" condition must be
absent before the drive will be allowed to run.
Selects the alarm message that will be displayed when a Low City
condition is detected.
0: Low City Pressure
1: Low Suction Pressure
2: Low Water in Tank
Parameter functionality stated below only applies when b1-01 = 5 (Geothermal Mode)
Sets the temperature that corresponds to a 0V (or 4 mA) analog input.
Sets the temperature that corresponds to a 10V (or 20 mA) analog input.
Frequency Reference (Hz)
Sets the frequency reference characteristics based on the set temperature
points and the corresponding frequency.
For proper operation, P4-34>P4-33 and P4-38>P4-37>P4-36>P4-35.
See Function Description for more information.
Selects the drive action when the signal from Terminal A2 has gone below
3 mA or above 21 mA. Only effective when H3-08 = 2
(4-20 mA) and H3-09 = 20 (Geothermal Temp).
0: Disabled
1: Alarm
2: Fault
