Setting 80: HAND Mode
Closing this input will put the drive in HAND Mode.
If this contact is closed within one second of power-up, the drive will honor the utility delay time.
Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.
Setting 81: HAND Mode 2
Closing this input will put the drive in HAND Mode using P5-05 as a frequency reference.
If this contact is closed within one second of power-up, the drive will honor the utility delay time.
Note: When inputs 80 and 81 are closed simultaneously, input 80 has priority and P5-01 determines the frequency reference.
Settings 83, 84, and 85: Alternate Multi-step Setpoints
These setpoint selections are different from Multi Setpoints 1 and 2 (H1-oo = 8D/8E) in that each input is dedicated to a
setpoint instead of being a binary selection.
Table 4.22 shows active setpoints based on the Alternate Multi-Setpoint Selections (H1-oo = 83 to 85):

Setting 88: Volute-Thermostat (N.O.)
Closed: Drive will trip on “VLTS - Volute-TStat Flt”.
Open: Thermostat fault not active.
Note: Assigning both 88 and 89 to input terminals will trigger a VLTS-Volute-TStat Flt.
Setting 89: Volute-Thermostat (N.C.)
Closed: Thermostat fault not active.
Open: Drive will trip on “VLTS - Volute-TStat Flt”.
Note: Assigning both 88 and 89 to input terminals will trigger a VLTS-Volute-TStat Flt.
Setting 8C: Disable Pre-Charge
Close to disable pre-charge.
Settings 8D and 8E: Multi Setpoints 1 and 2
Settings 8D and 8E will override all other PID setpoints when closed.

Setting 8F: Low Water Level
Function is active in AUTO Mode during normal operation and is also used with Pre-charge function.
Function depends on P1-30, Low Water Digital Input Configuration, setting.
When P1-30 = 0 (N.O.): Closed: Low Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: Low Water Level Fault.
Pre-charge function uses low water level input as “Tank/Reservoir” feedback to indicate water level reached.
