KNIGHT KTM-600 PMP Series Peristaltic Metering Pump System Instruction Manual

INTRODUCTION

The PMP Series peristaltic metering pump system is designed to dispense a variety of cleaning and sanitizing chemicals. Positive, accurate metering of liquids can be triggered manually or by a process control signal.

The PMP Series provides fixed speed output with the option of a programmable limit-timer. PMP is built with Knight’s field proven, long-life peristaltic pumps. Moisture sensitive motor and controllers are enclosed in a corrosion resistant, watertight, powder coated case that stands up well for indoor and outdoor applications.

RECOMMENDED OPERATING PARAMETERS

Pump Model| Duty Cycle| Maximum Pump Run Time| Maximum Lift (Suction)| Maximum Head Pressure
---|---|---|---|---
PMP-800 Series| 50%| 5 Minutes| 10 Feet (3 Meters)| 30 PSI (2 Bar)
PMP-900 Series| 10%| 5 Minutes| 10 Feet (3 Meters)| 30 PSI (2 Bar)
| | | |

NOTES:

The duty cycles and maximum pump run time specified above can be exceeded, however in doing so the life of the squeeze tube, roller block and motor will be reduced.

Fixed speed (AC drive) pumps have a thermal cut-out that will stop the pump if it overheats. The duty cycle of the
pump and ambient temperature contribute greatly to the overall run time capability, regardless of the maximum allowable time that can be set on the circuit board (if so equipped). If the thermal cut-out activates to stop the pum , the pump must cool down before it can resume normal operation.

SPECIFICATIONS

• Enclosure: Powder coated stainless steel.
• Pump Drive: Shaded pole AC.
• Squeeze Tube: Material available for most chemical applications.
• Control: Limiting timer available.
• Power Supply: 115VAC/60HZ, 230VAC/60HZ
• Dimensions: PMP-800: 9.3‖H x 5.8‖W x 5‖D (23.6cm x 14.7cm x 12.7cm)
  PMP-900: 13.6‖H x 8‖W x 7.5‖D (34.5cm x 20.3cm x 19.1cm)

THEORY OF OPERATION

The PMP Peristaltic Metering Pump can be operated as a stand-alone pump without any circuitry or is available with a limiting timer option.

• Basic models (no circuitry) will run the pump for as long as the power switch is turned on. See the notes in the Specifications‖ section above for details on the max run time.
• Time controlled models, detailed below, are available with a KTM-600 limiting timer.

KTM-600 — This pump ―Limit Timer‖ control is designed to control the run time of the pump with the press of a button or input of a signal from a powered switch or remote controller. The water proof control cabinet is normally mounted near the delivery point for the chemical, convenient for operators. Typical delivery points include Gerry cans, buckets, floor scrubbers, portable framers or other receptacles. For applications where remote triggers such as a CIP or Conductivity control signal are used, the controller can be installed close to the signal source. The signal-input circuit accepts input voltages from 14-240 VAC. The KTM-600 board also has a ―Relay Mode‖ feature that allows the pump to run from a 14 – 240V signal (for as long as the signal is present) or while the push button is held down. Using the relay mode with the push button is well suited for manual feed applications.

INSTALLATION

1. Check voltage of installation with a voltmeter and compare with voltage inputs of pump unit before mounting. Application of incorrect voltage will permanently damage unit and is not covered under warranty.
2. Mount unit on wall or shelf in a convenient location near both injection point and chemical supply. Do not mount unit in direct path of steam. This can short circuit and permanently damage your system.
3. Most systems include a power cord for easy connection. Rigid or flexible conduit can be used to ensure safety and continued operation without shorts. The green ground wire must be applied to ground. Failure to do so will void warranty.
4. Install braided tubing between the discharge (right) tube side of the peristaltic pump and the injection point. Use the provided stainless steel hose clamps and barb fittings to secure braided tubing to squeeze tube.
5. Install braided tubing between the suction (left) tube side and the barb fitting on the PVC pickup tube provided. Use the provided stainless steel hose clamps and barb fittings to secure braided tubing to squeeze tube.
6. Some units are equipped with an optional prime switch which can be used to fill the suction and discharge tubing connected to the pump. Depending on the model, the pump will either run as long as the prime switch is depressed, or will trigger a timed injection set on the control circuit board (if so equipped).

MAINTENANCE

The PMP Series of Metering Pumps require a minimal amount of maintenance to achieve optimal performance.
Periodically check the squeeze tube for cracks, deterioration, or swelling. The squeeze tube will typically need to be replaced about every 6 months (chemical compatibility and duty cycle can cause this interval to vary).

Applying lube to the squeeze tube once a month will extend the life of the tube, minimize wear on other contacting parts, and promote smoother pump operation. Use Knight Tube Lube (P/N 7506621) or an equivalent silicone based lubricant.

1. Remove the faceplate of the pump. Apply a thin bead of Tube Lube to the inner surface (the side that the rollers contact) of the squeeze tube between the 9 o’clock and 3 o’clock positions. Avoid getting lube near the pinch points where the bottom of the faceplate grips the tube.
2. Put the faceplate back on the pump.
3. Activate the pump under normal operation — the lubricant will be evenly distributed as the pump rotates.

MODELS WITH KTM-600

Pump Run Time: (max run time is 12 minutes and 42 seconds)

1. Locate the dip-switch pack on the circuit board — set switch #6 to SIGNAL, set switch #7 to RUN TIME and set switch #8 to PROGRAM MODE.
2. Using a measuring cup or beaker, press Start switch and release when pump starts. Let the pump run until desired amount of chemical is dispensed then press Start switch again to stop. The run time is now programmed. Repeat step if new volume is required.
3. Set mode switch #8 to RUN MODE.

Delay Time: (max delay time is 12 minutes and 42 seconds)

1. Locate the dip-switch pack on the circuit board — set switch #6 to SIGNAL, set switch #7 to DELAY TIME and set switch #8 to PROGRAM MODE.
2. Press Start switch and release when the LED begins flashing. When the desired delay time has passed, press the Start switch again. The delay time is now programmed. Repeat step if new delay time is required.
3. Set mode switch #8 to RUN MODE.

Lock-Out Time: (max lock-out time is 31 minutes) This feature defeats consecutive dispensing of product for a pre-determined interval. Select a combination of switches 1 – 5 to program total lock-out time.

Example: For 10 minute lock-out, set switches #2 and #4 to ON with all other switches OFF. For maximum lock-out (31 min) set all switches ON. For no lock-out, set all switches OFF.

OPERATION

Manual activation: Press the Start button for 1 full second. The unit will begin counting down the delay time (if used) and will then run the pump for the amount of time programmed. Once the lock-out time expires (if used) the pump will be ready to restart.

Signal activation: When the signal input on the circuit board receives a 14-240VAC trigger signal for at least 5
seconds, the delay time (if used) will begin counting down. Then the pump will run for the amount of time programmed. Once the lock-out time expires (if used) the pump will be ready to restart.

Relay Mode: Set switch #6 to RELAY. The pump will activate for as long as an external trigger signal is present, or for as long as the manual button is depressed. All other board functions (such as delay time and lock-out time) are by -passed in relay mode.

DISABLING THE START BUTTON

There is a jumper marked ―JP1‖ on the circuit board that can be used to prevent manual activation in certain applications, or to allow manual activation by remote push-button only. This jumper only affects the on-board start button. A remote start button, or trigger signal, can always be used to activate the pump.

• When the jumper is ON, the on-board start button is functional.
• When the jumper OFF, the on-board start button is disabled.

PRIMING

1. Locate the dip-switch pack on the circuit board and set switch #6 to RELAY.
2. Press and hold the Start button until the chemical line is fully primed, then release the button.
3. Set switch #6 to SIGNAL (unless you intend to use relay mode).
