MODEL SD203

DUAL CHANNEL MISSING TAB DETECTOR

Features...

• Push-button calibration optimizes settings and reduces time to set up.
• Microprocessor control provides better measuring resolution and reliability.
• Aluminum & Steel sensitivity eliminates the need to stock more than one model.
• Two detectors in one chassis provides a compact package and requires less panel space.
• Two digital displays to monitor relative thickness, signal strength and fault conditions.
• Diagnostic messages quickly isolate errors and failures in the detector and probes.
• Operating Power is standard 24 Volts DC.
• Six solid state transistor outputs for comprehensive control of Single. Double, No Tab, Tab & Channel Fault detection.
• Quick disconnect terminals decrease replacement downtime.

• Functionally compatible with early Prime & Hyde Park Models DS33, DS35, DS37,and DS38 and will fit in the same panel footprint.
• Optional communication port expands information to external systems.

. The New Model SD203 and its push-to-calibrate feature provides a simple and dependable way to begin monitoring can ends traveling through a conversion press. The Model SD203 is two detectors in one for use on each lane of a conversion press. This Double or Nothing detector along with two sets of probes installed at the discharge of each lane detects a missing tab. Each channel has three solid-state outputs. The three outputs energize for tab present, no tab and a detected fault (for example inoperative probe)

Calibrating the detector is simple. Just push the Calibrate push button for either channel after inserting an end with a tab between the transmitter and receiver probes. The Model SD203 will automatically measure and memorize the tab. Future ends missing a tab cause the No Tab output to turn-on. Calibration is that easy. All outputs are solid state transistor type and are configured with a jumper to sink or source current. There are no additional adjustments or fine tuning. Dual two-digit LED displays indicate probe signal strength or fault codes. Quick disconnect terminals provide fast and easy changeover . Operating power requirement for the Model SD203 is 24 volts @ 200 milliamperes DC. .

Specifications:

• Power Input: (required), Voltage: 24 V DC *10 % ripple Current: >350 mA.
• Logic Inputs external designated Calibration and Auxiliary 1 & 2. Hardware consists of jumper selected transistor type : pull-up mode for source drivers, pull down for sinking drivers. (AUX. changes frequency to steel or aluminum optimum sensitivity)
• Logic Impedance is 4.7K ohms, response to less than 1 m Sec.
• Switching thresholds: above 6.4V when going high, below 5 volts when going low.
• Probe Inputs tuned for Prime transmitter and receivers only for each channel.
• Outputs (6) Transistor types, designated Single, Double, Tab, No-Tab, 2-Fault Jumper select current sinking or source Source current limit at 160 mA, combined outputs. Source voltage: 22 Volts Sinking current: 100 mA Max. Sinking voltage: 30 Volts Max.
• Probe Types AY, AV, AZA, CB, CFB and all in P15 family for optimal operation, also works with AK, AVB, CA, CF and P70 family but not optimized for best operation.*
• Response Time 1 to 16 m Sec (Effected by the metal type and the thickness during calibration).
• Thickness Range 1 mm (.040") with P15CS, Varies with probe and separation.

• Probe Separation max 75 mm with P15CS.
• Max range not advisable when trying to detect pull tab. For pull tab detection use any of the probe types recommended under Probe Types with 16 mm (.625") separation. Do not use probes ending with S.
• Reject threshold. Factory set to 50% ON and 30% OFF of calibrated nominal.
• Displays Two channel, two digit alphanumeric LED display. During operation indicates signal strength and fault location. During calibration nominal value or calibration fault.
• Indicator Lamps consist of two channels of green for present and red for over or under nominal value. Also flash for faults.
