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.
