## Description

The TP1-IR wireless touch probe is used for precise workpiece setup and tool measurement on CNC machine tools or as a precision limit switch in automation. Signal transmission between the probe and receiver is via infrared light. The probe can be fitted with any touch stylus with M4 thread. To install the TP1 touch probe in the machine spindle (use as a workpiece probe), the CS16 clamping shank must be purchased separately — it allows precise centering of the stylus while the spindle rotates. For mounting the TP1 touch probe on the machine table (use as a tool probe), the BP58 base plate is available. When purchasing the TP1 touch probe together with the CS16 clamping shank, BP58 base plate and any touch stylus, you will receive a complete pre-centered assembly ready for immediate installation without further adjustment.

On the PH version the receiver cable is protected by a flexible conduit.

## Wiring

### Wire marking

| Signal | Conductor colour |
| --- | --- |
| GND | white |
| VCC | brown |
| TOUCH | yellow |
| READY | green |

### Output signal

Set on the switch on the receiver’s board, where the legend is printed too.

| Configuration | How it is set |
| --- | --- |
| NO / PNP — Factory | 1 Down, 2 Down, 3 Up |
| NO / NPN | 1 Down, 2 Up, 3 Down |
| NO / Push-Pull | 1 Down, 2 Up, 3 Up |
| NC / PNP | 1 Up, 2 Down, 3 Up |
| NC / NPN | 1 Up, 2 Up, 3 Down |
| NC / Push-Pull | 1 Up, 2 Up, 3 Up |

### Output signal timing

Timeline of the Touch and Ready outputs against the deflection of the stylus.

| Signal | High between (ms) |
| --- | --- |
| touch | 5 → 9, 13 → 18 |
| ready | ≥ 5 |
| stylus | 2 → 7, 11 → 16 |

## Operating Settings

The probe has two modes: standby and operating. Deflecting the stylus wakes it into operating mode and activates READY; after a set idle time it returns to standby.

### P1 — Duty cycle of the IR LED

Radiated power, set to the distance from the receiver. A higher duty cycle shortens battery life; the quoted range and battery figures are for the factory value.

| Value | Parameter |
| --- | --- |
| 10 % | P1 = 1 |
| 20 % (Factory) | P1 = 2 |
| 30 % | P1 = 3 |
| 40 % | P1 = 4 |
| 50 % | P1 = 5 |

### P2 — Transition to standby

Idle time from the last deflection before the probe sleeps. In standby it does not transmit and READY is inactive.

| Value | Parameter |
| --- | --- |
| 1 min (Factory) | P2 = 1 |
| 2 min | P2 = 2 |
| 10 min | P2 = 3 |
| 20 min | P2 = 4 |

### Programming procedure

1. Remove the battery. Tilt the stylus and hold it.
2. Still holding it, insert the battery and screw on the cap. Green LED on.
3. After 2 s, green goes out and red comes on.
4. Release the stylus. Green for 1 s, then off — ready for P1.
   > If green flashes instead, programming mode was not entered — start again.
5. Touch the pad once per unit of P1, each touch under 0.5 s. Red follows the pad.
6. Hold for over 1 s to confirm. With no short touch first, P1 is unchanged.
7. Green flashes back the value of P1.
8. Green for 1 s, then off — ready for P2. Same procedure.
9. Green flashes back the value of P2.
