RAVEN SID-20200 Portable Sludge Interface Detector

Product Usage Instructions

1. Press the POWER button to activate the display.
2. Lower the probe until it just contacts the tank bottom.
3. Place the cable on the COUNTER ROLLER.
4. Press the ZERO button to reset the display value.
5. Raise the probe until the INTERFACE lamp illuminates.
6. Note the PROBE TRAVEL distance.

USING THE SID-20200

• Press POWER button to activate display Lower probe to just contact tank bottom Place cable on COUNTER ROLLER
• Press ZERO button to reset display value Raise probe until INTERFACE lamp illuminates Note PROBE TRAVEL distance

IMPORTANT

• Store the probe on the case handle hook, while carrying the unit.
• Probe stored on hook prolongs the life of the cable and probe.
• Wrap cable loosely on cable rack to prolong cable.

The NEW SID-20200 replaces the SID-10200 with upgrades that include Side mounted counter roller that measures probe travel

• Digital display that is visible at night
• Switchable Inch or millimeter display units
• Auto sleep preserves batteries
• Easy clean faceplate with tactile buttons
• Light weight and ultra-smple to use

TOOL FAMILIARITY

• POWER button activates unit
• ZERO button resets travel value
• SENS button toggles probe sensitivity
• HORN button enables horn
• PROBE TRAVEL updates when cable passes across roller
• INTERFACE lamp illuminates when probe sensor obstructed
• HORN sounds when enabled and probe sensor obstructed
• SENS display indicates current sensitivity setting
• LOW BATT displays when battery change required
• The displayed SENS value indicates the probe sensitivity setting.
• The SENS button cycles LOW, MED and HIGH sensitivity settings.
• LOW sensitivity ignores relatively small solids, but detects large solids.
• HIGH sensitivity detects relatively small and large solids.
• When solids detected, the INTERFACE lamp illuminates and the horn sounds.

SLUDGE INTERFACE DETECTOR SID-20200 SPECIFICATIONS

QUICK CHECK

• Press POWER button.
• Press HORN to button to enable.
• Place your finger over a probe sensor len.
• The INTERFACE lamp illuminates and horn sounds.
• The horn can be switched-off without affecting unit operation.

BATTERY REPLACEMENT

• Batteries are located inside the case head.
• Remove the case faceplate four screws.
• Remove the faceplate from the case and leave wire attached.
• Slide the black battery pack out of the case holder.
• Remove battery pack cover.
• Replace all three AAA batteries with new alkaline batteries.
• Slide the black battery pack into the case holder.
• Install case faceplate with original screws snug tight.

SENSOR ADJUSTMENT

• SENS “LOW” – Detects large solids only
• SENS “MED” – Detects intermediate and larger solids
• SENS “HIGH” – Detects all solids

FINE-TUNING SLUDGE DETECTION

• When you’ve established a baseline sensitivity for a tank, you can fine-tune by increasing and decreasing the sensitivity above your baseline.
• At sensitivities higher than your baseline, you can detect the ragged edge on top of the sludge blanket.
• Sludge blankets rarely have a well defined interface with the supernatant. Experience with the SENSOR ADJ will allow the keen operator to measure the ragged edge of the sludge blanket. It is not uncommon in a
• dynamic environment such as a secondary clarifier to identify several feet of gradual density change on top of the sludge blanket.

CABLE REPLACEMENT

• The cable and probe are one assembly and can be replaced in the field.
• Contact Raven for replacement parts and probe assemblies.
