Kitchen-Triever General Product Specifications

 

  1. Power Requirements

    2. The KITCHEN-TRIEVER requires a single phase grounded electrical service of 20 amperes with a voltage of 105 VAC to 125 VAC from 50 to 60 Hz. Motor has an intermittent duty rating of 1 ½ HP, Maximum Current Rating: Max. Amp. 14.4. Unit is equipped with a 16-amp circuit breaker. The power cord is 7’ long from point of exit (lower right rear of unit) to electrical outlet.

  2. Human Factors

    3. The controls are located within arm’s reach from a seated position.

    The access opening is adjustable within the range of 34"– 39" from the floor level, depending on the desired design. The on/off switch is positioned

    accordingly, 34"–39" from the floor, and the operator control is 36"–41", dependent on the height at which the access opening is fixed.

  3. Safety

    4. Safety devices are designed to stop the conveyor system if any obstruction exists between the carrier and the access opening. These devices are designed to be "fail-safe". Two non-identical systems are incorporated to provide redundancy. Maximum safe stopping distance of the conveyor system is less than one (1) inch.

    3.1 The safety system is comprised of an infra-red source and detector located at both

    corners of the upper and lower access opening.

    3.2 A second safety system is comprised of a "floating safety bar" located at

    both the top and bottom of the access opening.

    3.3 Should either of the safety systems described in paragraphs 3.1 and 3.2 be activated, the system will stop its movement.

  4. Carrier positioning

The drive assembly is operated from the control console of the unit, located on the right side of the access opening, from the operator’s viewpoint. In the event of a power failure, the unit may be operated manually, with the included ratchet tool. A safety microswitch deactivates the unit if it is being operated manually.

5.0 Controls

Each Kitchen-Triever unit is equipped with an up/down control, which enables the operation of the movement of the carriers in either an upward or downward rotation.

 

 

5.1 Master On/Off Switch

Depressing the "ON" switch will turn the unit on. If the ON/OFF switch fails to light, verify that the power cord is plugged into an electrical outlet. The unit may be turned off at any time.

5.2 Optional Interfaceable Keyboard Console

The keyboard console provides complete control to scan or select media stored in the unit. The console consists of a numeric touch pad, display, and index windows.
    1. Clear Key:

      2. Any level selection entry may be cleared or canceled by depressing "CLEAR". A new level selection may then be entered.

    2. Level Selection:

      3. A level may be selected by entering one or two digits of the selection and depressing "ENTER". The selected level will be immediately brought to the posting position.

    3. Scanning:

      4. Levels may be scanned at any time by depressing either "UP" or DN". Scanning will stop when the key is released.

    4. Memory:

      5. In addition to the normal memory during scanning, any displayed selection may be temporarily stored for later recall. One of two memory modes may be selected during installation; Single Reference or Multiple Buffer Mode.

      1. Single Reference Mode:

        2. Any displayed selection may be temporarily stored in memory for later recall. The selection is not erased from memory when recalled; it will remain in the memory until another selection is stored.

      2. Multiple Buffer Mode:

      Up to 16 selections may be temporarily stored in memory. Selections will be recalled in the order they were stored. Each selection is erased from memory when recalled.

    5. Safety Functions:

      6. The unit will abruptly stop if any safety system has been activated.

    6. Audible Signal:

A short tone confirms each key entry.

g. Load Indicator:

The display will flash once per second plus an audible signal when the media

weight being lifted is more than 80% of the maximum imbalance allowed for the unit. The maximum allowable imbalance is 600 pounds.

h. Diagnostic Indicator:

The display flashes codes to assist in diagnosing electronic malfunctions.

5.3 L.E.D. readout window.

The L.E.D. readout will visually display in ½" high characters the carrier

number selected for access.

 

6.0 Control Circuits

The control circuits are solid state and designed with a modular concept. The control circuits are designed to be readily accessible from the right front of the unit.

a. Wiring from the keypad logic board is of the ribbon cable type with connector for fast, reliable maintenance.
  1. The system key-pad and other major electronic components are designed to

    2. be easily removed or replaced.

  2. The interfaceable control is designed to provide movement through the shortest path for bringing carriers to the posting level.

7.0 Conveyor Imbalance

The conveyor system is capable of transporting loads up to 600 lbs.

maximum imbalance condition.
  1. Additional Safety Devices

Additional safety switches control the lower access panel to prevent the machine from automatically operating while these panels are not in place.
  1. Mechanical Drive and Guide Components

    2. Vertical Drive Conveyor Chains are American Standard #80-1" pitch. The chains are precisely guided throughout the entire vertical drive to assure quiet operation.

  2. Carrier Stabilization Tracking

    3. All carriers are stabilized through the use of four stabilizing rollers. These rollers move within two track systems. The primary track system is located at the top and bottom, left and right on both column supports. A second internal vertical track combines efficient and controlled stabilization of the carriers in their rotation.

  3. Cycle Time

14 carriers per unit

14.0 Noise

The Kitchen-Triever will not exceed 55 decibels when loudness is tested within one foot.

  1. BTU’s Per Hour Average:
    1. Average current for all load conditions is approximately 8 amps.
    2. Approximately 60% of input energy is heat:

Continuous BTU input = 3275 BTU’s/ hour x 60% =1965 BTU’s hour (continuous) heat

20 watts idling = 68.25 BTU’s/hour heat

(2 ½% usage) average running BTU’s (.2 hours/day) = 47.4 BTU’s hour (excludes idling)

2 ½% usage RUNNING AND IDLING = 115.65 BTU’s /hour heat
