Coolant Refill - Operation, Maintenance

Applies to machines built from: 
April, 2015
AD0172 Rev D

Overview

The Coolant Refill assembly does these tasks automatically:

  1. Mixes water with coolant concentrate.
  2. Adds coolant to the coolant tank.
You can set values that control how the Coolant Refill operates. This decreases the work necessary to keep the correct level and concentration of coolant in your tank.

Components

  1. Coolant concentrate container
  2. Water supply hose
  3. Coolant Filler pipe/hose

Use these types of coolant concentrate for the Coolant Refill:

  • Soluble oil
  • Synthetic
  • Semi Synthetic

Requirements

  1. Classic Haas Control: Mill software 18.22A or higher and lathe software 11.18A or higher.
  2. Next Generation Control: Software 100.16.000.1010 or higher.

Installation

Refer to the Coolant Refill procedure.

Classic Haas Control Operation

The COOLANT REFILL [1] page shows the Coolant Refill settings. These settings control the operation of the Coolant Refill.

Do these steps to go to the COOLANT REFILL page.

Push CURNT COMNDS. Push PAGE DOWN until the COOLANT REFILL page shows.

To set a value:

Push the UP or DOWN CURSOR arrows to highlight a setting. Enter the value. Push WRITE/ENTER.

Settings for the Coolant Refill:

Setting Description Default Value Range
Estimated gallons of coolant consumed per hour [2] This is the quantity of coolant lost to the environment in an hour of detected coolant use.* 1.0 .01 - 99 gallons/hour
Coolant concentration percent [3] This is the correct coolant concentration necessary for the application. 5 0 - 10 %
Number of hours between refills [4] This is the quantity of time between automatic coolant refills. 5.0 0.1 - 999.8 hours
Max gal. coolant added before replenishing concentrate [5] This is the quantity of coolant mixture that flows into the coolant tank before the coolant concentrate container is empty. 500 20 - 1000 gallons
Gallons per minute supply water [6] This is the quantity of water flow from the water supply. Measure the water flow from the water supply and enter that value here. 2.0 0.1 - 99.9 gallons/minute
Coolant Concentrate adjust percent lean [7]

This is the accurate adjustment of the measured coolant concentration. Increase or decrease this value to make the measured coolant concentration the same as the value in Coolant concentration percent [3].**

0 (-20) - 20
Coolant level sensor gauge [8] This gauge shows the level of coolant mixture in the coolant tank. N/A N/A
Low coolant concentrate warning [9]

This REFILL CONC. icon shows when the value in Maximum gallons coolant added before replenishing concentrate [5] becomes 40. This lets you fill the coolant concentrate container before it becomes empty.

When the value becomes 0, the Coolant Refill system operation stops. This lets you fill the coolant concentrate container.

To keep the system in operation, fill the coolant concentrate container before it becomes empty.

N/A N/A

*The control monitors coolant use as the quantity of time the pumps are on.

**Refer to the Coolant Refill - Calibration procedure.

Next Generation Control Operation

The Coolant Refill page shows the Coolant Refill Settings [1]. These settings control the operation of the Coolant Refill.

Do these steps to go to the Coolant Refill page.

Push DIAGNOSTIC.

Push the RIGHT CURSOR arrows to select the Maintenance tab.

Push the DOWN and RIGHT CURSOR arrows to select the Coolant Refill tab.

To set a value:

Push the UP or DOWN CURSOR arrows to highlight a setting. Enter the value. Push ENTER.

Settings for the Coolant Refill:

Setting Description Default Value Range
Coolant Refill [2] This setting activates or deactivates the Coolant Refill option. Off On or Off
Estimated Coolant Use Per Hour [3] This is the quantity of coolant lost to the environment in an hour of detected coolant use.* 1.0 .01 - 99 gallons/hour
Coolant Concentrate [4] This is the correct coolant concentration necessary for the application. 5 0 - 10 %
Time Between Refills [5] This is the quantity of time between automatic coolant refills. 5.0 0.1 - 999.8 hours
Maximum Coolant From Remaining Concentrate [6] This is the quantity of coolant mixture that flows into the coolant tank before the coolant concentrate container is empty. 500 20 - 1000 gallons
Supply Water Rate [7] This is the quantity of water flow from the water supply. Measure the water flow from the water supply and enter that value here. 2.0 0.1 - 99.9 gallons/minute
Concentrate Adjustment [8]

This is the accurate adjustment of the measured coolant concentration. Increase or decrease this value to make the measured coolant concentration the same as the value in Coolant concentration percent [3].**

0 (-20) - 20
Coolant Level [9] This gauge shows the level of coolant mixture in the coolant tank. N/A N/A
Low Coolant Concentrate Warning [10]

This Low Concentrate icon shows when the value in Maximum Coolant From Remaining Concentrate [6] becomes 40. This lets you fill the coolant concentrate container before it becomes empty.

When the value becomes 0, the Coolant Refill system operation stops. This lets you fill the coolant concentrate container.

To keep the system in operation, fill the coolant concentrate container before it becomes empty.

N/A N/A

*The control monitors coolant use as the quantity of time the pumps are on.

**Refer to the Coolant Refill - Calibration procedure.

Maintenance

Coolant-Concentrate Filter Cleaning

  1. Remove the cap [1] from the container.
  2. Find the filter screen [2] inside at the bottom of the container. Remove the filter screen.
  3. Clean the filter screen with water.
  4. Install the filter screen and cap onto the container.

Be aware: Many service and repair procedures should be done only by authorized personnel. The service technicians at your Haas Factory Outlet (HFO) have the training, experience, and are certified to do these tasks safely and correctly. You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes.

Danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not completely understand. Contact your Haas Factory Outlet (HFO) and schedule a service technician visit if you have any doubts about doing a procedure.
