Mounting and Wiring

Mounting

CAUTION

Do not mount in direct sunlight.
Use flex conduit between rigid conduit and SVS 2000 enclosure.
Consider clearance needs for wiring and maintenance.
Consider temperature at mounting location. See Manual Appendix A for specifications.

For Stainless Steel version, first remove electronics assembly.
Hold SVS 2000 in desired location and mark mounting hole positions.
Drill mounting holes.
See Manual Appendix E for additional wiring details
Detail — KM Half-Bridge Sensors
Mount SVS 2000 securely using customer-supplied hardware.
For Stainless Steel version, make entry holes in bottom of enclosure and re-install electronics assembly.

Wiring

Route AC power and setpoint cables separate from low-level signal cables.

Connect sensor wiring.
Connect relay output, digital output, analog output, serial output, and remote input wiring, as applicable.
Connect AC power.
Apply power and check display.
Seal openings in enclosure, using Sikaflex 1A or Dow Corning RTV 739 or 738 sealant.
Tighten set screws that secure wires to the terminal boards to 8 lbf/in. of torque.

WARNING

Wiring must comply with national/local wiring requirements.
Ground conductor must connect to Protective Earth (PE) terminal. Power wiring must include switch/circuit breaker for disconnecting power. It must be close to SVS 2000, in easy reach of operator, and marked as disconnect for unit.

Setup with Quick Config

See Figures 1 and 2. Determine whether application is direct support or bolt-on. Gather data to fill out table in applicable figure.
See Figure 3. Perform Quick Config. SVS 2000 leads you through menu tree. When Quick Config is complete, SVS 2000 automatically switches to Run Mode.

Notes:

See load cell label or sensor manual.
Enter number of supports, not number of load cells. For example, in the suspended application shown above, there are
supports (3 rod assemblies), even if only 2 of the assemblies contain live load cells.

(Microcell or L-Cell) Application

Auto (Live Load ) Calibration

Quick Config configured the SVS 2000 based on system and sensor characteristics. When scheduling permits you to move material (at least 25% of vessel’s capacity), perform Auto calibration to obtain highest accuracy.
Calibration by Adding Known Quantity of Material (starting on Run Mode display)

Note: For Calibration by Subtracting Known Quantity of Material, see Manual Chapter 6, Cal Menu.

Default Unit
Method #1 (starting on Run Mode display)

Method #2

Turn off AC power.
Press and hold Enter Key while turning on AC power.

Remote Tare or Totalize

Provide a 1 second contact closure on tare input terminals — see Manual Appendix E for wiring details. Configuration of remote input as tare or totalize is done in function 15, Ext Inpt Mode.

Error Messages

Menu Descriptions

Display Menu
Disp Format — Move decimal point or add ‘dummy’ zeroes to display.
Use with Disp Countby to provide results consistent with system accuracy.
Note that changes affect many parameter values.
Disp Countby — Set display to count by increments.
Disp Units — Set engineering units for display.
Bargraph Span — Set span
(100% value) for bar graph.
Ext Inpt Mode — Configure
external input as remote tare
(default) or remote totalize.

Cal Menu

Auto Cal —
- Set Lo Span and Hi Span while
  moving material into or out of
  vessel. Must move at least 25% of
  vessel’s total capacity. Provides
  highest accuracy.
- Set known material weight with
  Disp Val Correct to shift calibration.
Manual Cal — Fine tune calibration using calculated values or re-enter previous calibration data.
Linearization — Correct weight for vessel structures that respond non-linearly to load changes.
Zero Tolrance — Set tolerance limit for pressing of Zero Key in Run
Mode (gross weight display) to prevent accidental zeroing of vessel with material.
Cal Display — View calibration values.
Setpoint Menu
Set up relays and digital outputs:
Value — Energizing value.
Deadband — Material added or removed before setpoint de-energizes.
Hi/Lo — Energize above or below Value.
Track — Energize based on gross,
net, or total weight, or system fault.
• Failsafe — Setpoint failsafe condition (on, off, or no change)
• Preact — Point (material added or removed) before Value is reached at which setpoint energizes.
