HYDROVAR
Pump Control
Quick Start Guide
Startup of a Hydrovar drive or Packaged Hy-
drovar Pump/Drive. Consult IM223 for recom-
mended system design, including pump, valves,
transducer, and diaphragm tank. For additional
applications, consult IM223.
Must be installed by qualified personnel.
1. Align drive on 3 Ph/TEFC motor and attach to mo-
tor using 4 clamps and screws provided. Remove
cover.
2. Verify power is off before connecting to drive.
Attach power wires to pump mounted fused
disconnect (if packaged product) or from wall
mounted fused disconnect or breaker box. Use
fast acting Class T fuses. Route wires through
cable gland, conduit plate – large opening –and
through cable gland nut.
3. Attach Power wires to drive: Attach ground wire
to ground screw. If 1 Ph, attach L and N to ap-
propriately labeled terminals. If 3 Ph, attach wires
to appropriate L1, L2, L3 terminals. See IOM for
terminal locations.
1 Ph 2, 3 HP
3 Ph 3, 5 HP
3 Ph 7.5, 10, 15 HP

- START/STOP
(D) RS-485 Interface
(E) Status-Relays
- SOLORUN
- User interface
- RS-485 Interface
- Internal interface (F) Optional
Relay Card
4. Drive connection to motor: Route wires through
cable gland and other large conduit opening as
above. Connect wires to appropriate terminals.
Use crimp-on spades for sizes 2, 3, 5 HP. Termi-
nate wires at terminals U, V, W for sizes 7.5 HP
and up.
*** Route the following low voltage wires
through small conduit glands and openings as
needed. ***
5. Attach transducer wires to terminals X3: 1-3;
Shield, White, Brown respectively.
6. Attach thermal overload switch to motor body at
conduit box screw, and terminate at the 2 termi-
nals labeled X1 PTC. If not using Thermal over-
load switch, place jumper between PTC terminals.
7. Provide Emergency stop switch, or jumper be-
tween terminals X3: 7, 8.
8. Provide additional on/off switch or jumper be-
tween terminals X3: 11, 12
9. If using multiple communicating drives, attach
RS485 wires to terminals X4: 4-6, (-, +, Shield
respectively) on Master drives; X2: 1-3 on Basic
drives. Daisy chain communication wires starting
at Master drive to all additional drives.
10. Verify all connections are secure with no stray
wires. Attach ground wire from drive to cover
and replace cover. Note: Be sure cover sits secure-
ly on drive without pinching any wires. Securely
HAND TIGHTEN cover screws. Cover must be
firmly attached for buttons to function properly.
11. Connect power. The display should look as
follows:
12. See attached flowchart for available program-
ming options to change.
13. Push Right arrow to next screen to change Set-
point. Use Up/Down arrows to change setpoint,
(Required value).
14. Push left arrow once to get back to main screen.
Push left arrow again to get to Main menu. Use
Down arrow to scroll through menu options. To
change any parameter other than set point, you
must first enter a password. From main menu,
scroll down to Group 60, and push right arrow
once to parameter 61. Enter password using up
arrow key, (password = 66).
15. For multipump programming, change the high-
lighted parameters in the flowchart. Change:
Parameter 105 to “Cascade Serial”; set the pump
address to 1, 2, etc in parameter 106.
16. From main screen, press up arrow to start drive.
Check rotation on pump. Switch 2 of 3 line wires
from the drive at motor if reverse rotation.
