1. Login & User Roles

Accounts & Security
The system requires at least one Administrator.
Multiple Administrators, Programmers, and Operators may be defined.
Login uses “Clock #” (case-sensitive; alphanumeric).
Change a user’s security level without recreating their account. (User must log out/in for changes to apply.)
Keep Admin/Programmer codes private to prevent unauthorized parameter/program changes.
Access Levels
Level 1 – Operator: Run programs only.
Level 2 – Programmer: Create/edit/delete programs (no parameter access).
Level 3 – Administrator: Full access, including parameters.
Operator Login
Operators must log in at software start. Access to functions is determined by the user’s Security Level.
Software / Machine Exit Options
- Exit to Windows: Admin only (either already logged in as Admin or supply Admin code at prompt). Use for PC/OS servicing only.
- Shut Down Bender: Normal end-of-day shutdown. Turns the PC off and disables all machine functions; pump turns off automatically.
2. Start-Up & Shutdown

Switch to Auto or Semi on the console.
Open the desired part program.
Follow on-screen prompts to begin bending.
Bender Shutdown (Daily)
Two safe methods. Both will stop the pump and power down the PC:
File → Shut Down Bender: Turns off pump and electronics, then powers down the PC.
After PC is fully off, turn off the main disconnect.Press Emergency Stop: A Shut Down Bender screen appears. Click Shut Down Bender.
After PC is fully off, turn off the main disconnect.
Important: Never switch off the main disconnect before the PC has shut down; this can damage the PC.

3. Homing/Referencing
All axes must be homed before running programs. Switch the console to Manual to home.
Swing Arm
- Jog the swing arm forward ~15°.
- Click Reference Swing Arm.
The arm moves to the limit switch, then to the home offset and final stop. Readout shows 0.0° and the button grays out when complete.
Stop Table (Single-Stop)
Jog the stop table forward ~10 in beyond the home switch.
Click Reference Stop Table.
Button turns blue while active; gray when complete.
Stop Table (Multi-Stop)
- Jog the stop table forward ~10 in beyond the home switch.
- Click Reference Stop Table, then YES to home all stops (1…12) to the rear of the rail.
Button turns blue while homing; gray when complete.
4. Programs
Create a New Part Program
File → New.
Navigate to target folder.
Name the program, e.g.,
MyFirstBendProgram.cnc
.Click Open to create a blank file.
All program files must use the .CNC extension.

Program Structure & Rules
- Programs consist of Stops (stop table positions) and Bends (angles + speeds).
- Bend Speeds: 1–100% of max speed.
- Stop 1 is always Absolute.
- Absolute Mode (Abs): All stops measured from spindle center.
- Incremental Mode (Inc): Stop 1 is absolute; subsequent stops measured from the previous stop.
- Bend Angles: 1° to the Max Bend Angle parameter (default 183°).
Global Adjustments (non-destructive)
Adjust all bends or all stops without changing the program:
Global Bend Adjustment: Apply over-bend to compensate for material springback.
Global Stop Adjustment: Apply cut-length corrections across all stops.
Automation Options
Auto Return to Stop 1 (Single-Stop tables only): After the last bend, returns to Stop 1.
Safe Retract Position: On the last bend, retract the stop table to an absolute “safe” distance from spindle center before bending to clear tooling.
Sequence: Operator presses Bend → clamps close → Stop Table retracts & moves to safe position → bend completes → arm returns home → (optional) auto-return to Stop 1.

Edit an Existing Program
File → Open and edit settings. Save to keep changes.
Run a Program
Reference arm & table in Manual (skip if already homed).
Switch to Auto or Semi.
(Optional) Enable Auto Return to Stop 1 and/or Safe Retract Position.
Open the program file.
Single-Stop table: If “Auto Return to Stop 1” is checked, the stop automatically moves to position 1.
Multi-Stop table: System prompts to place all stops to programmed positions.
Press & hold both Bend buttons to start the cycle; you may release after cycle starts (unless “Require hold” is enabled—see Machine Options).
Modes
Auto: Clamp → Bend → Unclamp → Auto return to home.
Semi: Clamp → Bend → Unclamp → Press both Bend buttons again to return arm to home.

9. Datasheet & Machine Setup
Stop Table Setup
- Zero Offset (critical): After homing, measure distance from Stop 1 front edge to spindle center and enter in Zero Offset. Re-home and verify.
Re-set only if the stop table is moved forward/backward. Lateral moves do not affect Zero Offset. - Travel Limit (Multi-Stop only): In Machine Options, click Acquire Table Travel Limits to auto-index from home to +OT and record the distance.
Needed only if table length changes.
Bend Arm Setup
Home Offset (negative):
Set Arm Home Offset to 0, turn pump ON, switch to Manual, reference the arm.
Measure the small remaining distance to the hard stop.
Enter negative offset in –2° steps; re-home until the arm just contacts the rubber hard stop. (Do not over-compress.)
10. Sub-Systems
Bend Arm Lube Pump
Lubes swing arm and clamp gibs every N bends (per Lube Cycle Counter).
Lube Cycle Time sets pulse duration (factory ~200 ms).
Pump output set to 2 cc (factory). If ways drip, increase Lube Cycle Counter (do not reduce pump below 2 cc).
Low lube level triggers a software alarm.
Oil: Conoco Multi-Way Machine Lubricant.


Air Line Lubricator
Lubes all air devices; check every 3 months.
To fill: Lift/turn right reservoir to release and remove.
Oil: Conoco Velocite Oil #3.
Sight gauge on reservoir indicates level.

Hydraulics
Reservoir ~40 gallons. Oil: A/W 46 (Citgo).
Flow (front lock bolt): Factory set—do not adjust.
Pressure (rear/side locked bolt): Set to 1000 psi max (do not exceed).
Swing arm speed is controlled by software, not flow/pressure screws.
Hydraulic Filter: 10-micron element with clog sensor. Replace annually along with oil to protect the servo valve.
To replace: Pump OFF, close main valve, remove canister, replace element.
[Images: Hydraulic unit • Filter & sensor]
11. Safety Plate
Dual-sided yellow swing-arm safety plates stop the arm and turn off the pump if pressed.
Wired in series with the Emergency Stop—both must be released for the pump to start.
Test by pressing either plate; pump should stop and motion cease.
Adjust trigger via the two angled cogs and switch base plate if needed.
[Images: Safety plate trigger switch • Adjustment points]
12. Diagnostics
Quick Diagnostics (View Control Signals)
End-user view for key inputs (limits/pushbuttons).
Some inputs require E-Stop released to function.
Full Machine Diagnostics (Technician)
Displays all Inputs / Outputs / Control Signals / Master Flags.
Set Bit tool toggles outputs for testing (technician only—hazardous).
Program 0 & 1 Current Line shows controller execution lines.
Print button prints the current signal grid.
[Images: Diagnostics overview • Machine I/O screen]
13. Alarms
Low Air Pressure: Triggers below ~80 psi. Stop table devices may malfunction below this pressure.
Setpoint adjustable on the internal switch (trip near 80 psi, restore ~60–70 psi).Change Hydraulic Filter: Filter backpressure high or element damaged. Replace filter.
Lube Oil Low: Refill the lube reservoir to MAX with Conoco Multi-Way Machine Lubricant.

14. Troubleshooting
Pressure Drops Below 450 psi (Bend slows/jerks)
Likely accumulator discharged; recharge to 500 psi nitrogen. Accumulator must be removed for recharge; cannot ship charged by carrier.
Located in the chain/bend cylinder compartment on top of the bender.
Erratic Stop Table Motion (Single or Multi-Stop)
Loose Table Belt: Tension at mid-belt; ~0.5 in vertical travel; do not drag or flop.
Incorrect Gains/Speeds: Compare to OEM datasheet and restore.
Single-Stop specific
Marks/scratches on rail near locking pad → Stop Unlock Delay too short (default 500 ms).
Multi-Stop specific
Lock not engaging/disengaging → Stop Unlock Delay too short or air < 80 psi.
Erratic Bend Arm Motion
System pressure 900–1000 psi and accumulator 500 psi required.
Check arm encoder chain tension.
Check encoder readout stability at rest; verify angle change during moves. Replace encoder if noisy/unstable.
Verify arm chain is tight (no flex). Re-check Arm Home Offset after chain adjustments.
Compare Gains/Speeds to OEM datasheet; incorrect values can cause errors and damage the servo valve.
Clamp Problems
Clamps/Drawbar use dual-ended 24 VDC solenoids. For one motion to occur, the opposing solenoid must release to center.
If clamp won’t release (or vice versa):
Test Manual Mode clamp/unclamp. If OK, check clamp delays in parameters (not zero).
Observe relays & solenoid lights during clamp/unclamp. Replace failing components as needed.
Relay/Solenoid Logic Reference
System Clamp Forward (Clamp Fwd / Drawbar Down) Clamp Reverse (Clamp Rev / Drawbar Up) Benders ≤ 20025 CR2=ON (Sol A), CR3=ON (Sol B), CR4=OFF (Sol B), CR5=OFF (Sol A) CR2=OFF (Sol A), CR3=OFF (Sol B), CR4=ON (Sol B), CR5=ON (Sol A) Benders ≥ 20026 Safety Relay ON (K10.171 & K10.91), K10.021=ON (Sol B), K10.031=OFF (Sol B), K10.041=OFF (Sol A) Safety Relay OFF (K10.171 & K10.91), K10.021=OFF (Sol B), K10.031=ON (Sol B), K10.041=ON (Sol A) Location notes:
Solenoid A = front solenoids. Drawbar valve closest; middle valve = clamps; furthest = hydraulic servo valve (bend arm).
If relays follow the table but action fails, suspect the solenoid. Minland recommends replacing all four relays together if one fails.
