I. Preliminary Steps

Follow these steps before attempting to service the SCA

Power off and disconnect the SCA from the main power.

Allow the SCA to cool completely.

Attach a hose to the front valve and drain the tank completely.

Always disconnect the SCA from the main power and drain the tank

completely before servicing.

7755 S Research Dr., Suite 105, Tempe, AZ 85284

II. Quick Troubleshooting

The SCA has been designed to allow the end user to resolve most operating problems. When a problem is

encountered, please read through this repair manual. If a resolution is not found in this manual, please

contact technical support.

High Risk of Electrical Shock

Always disconnect the unit from power

before removing any cover!

Problem

Probable

Causes

What to Do

No Power To SCA.

Power switch

is not “On”

Press rocker switch on the right-hand side of the unit to the “On”

position.

Power cord

is not

connected to

unit or wall

Check the power cord and make sure it is pushed all the way into

the receptacle on the system and is securely connected to a

grounded wall socket.

F2 Fuse is

blown

With power disconnected, check fuse F2 (2A 250V) on the PCB. It

may be visibly blown or use a multimeter to check the continuity. If

the resistance shows infinity (open), it needs to be replaced (See

How to Replace the F2 2A 250V Fuse Section XI). If the new fuse

blows again, troubleshoot the pump and transformer

(See Pump and Transformer Troubleshooting Section XII A).

Power circuit

breaker has

tripped

Check for ~110V AC (230V AC Europe) at the power plug and outlet.

If there is no voltage, check your building’s circuit breakers and any

power strips that the unit is plugged into for a tripped circuit breaker

or blown fuse. Reset or replace the breaker or fuse as required.

7755 S Research Dr., Suite 105, Tempe, AZ 85284

Problem

Probable

Causes

What to Do

Pump will not start,

SCA is powered up,

display panel is lit.

Timer has

not been set

and started

The system will only run when the timer is counting down. Check the

timer display on the control panel.

If it is not counting down, press the button. If the time being

displayed is 00:00, then add time and start the system as described

in the User Manual.

Pump or

transformer

is defective

(See Pump and Transformer Troubleshooting Section XII A).

Start Cap is

defective

(See Pump and Transformer Troubleshooting Section XII A).

PCB is

defective

(See No Power to SCA Troubleshooting Section XII A).

Start / Pause

switch is

defective

Replace Control Panel.

(See Display Control Panel Replacement Section VIII).

Problem

Probable

Causes

What to Do

Warning Indicator

Flashing

High Water

or Low Water

Indicator flashing

Liquid level

is too high or

too low

Check the indicator lights on the right side of the display control

panel. If either level indicator is on, add or remove water from the

tank until the indicator turns off.

ALWAYS WEAR PROTECTIVE GLOVES AND EYEWEAR WHEN

ADDING OR REMOVING LIQUID FROM THE TANK.

Basket is

raised or

lowered too

quickly

If the basket is lowered into or raised out of the cleaning solution too

quickly, the solution does not fill or empty out fast enough to maintain

even water level throughout the tank. This causes a temporary high

or low water level condition. The alarm will silence once the water

level reaches acceptable limits, but the unit will not operate again

until the button is pushed.

Float is stuck

on shaft

Remove float (See Sensor Assembly Replacement Section V)

and inspect. If there is a buildup on the shaft that inhibits the free up

and down motion of the float, clean off the shaft. A scrub pad can be

used to remove any buildup on the shaft. Ensure the float moves

freely from the bottom to the top of the shaft.

Water level

sensor is

defective

(See Water Level Sensor Troubleshooting Section XII F).

Error Code Displayed

Internal Error

Sensor failure, power supply failure, or pump failure.

(See Error Codes Section XII).

Error Codes:

*EP = Pump motor current fault

*EH = Heater current fault

ES = 12VDC out of range, power supply error

EO = Over temperature

r1 = Temperature sensor failure

r2 = High level sensor failure

r3 = Low level sensor failure

*Only displayed on the original controllers without the “No Heat” option

Not Heating, no errors,

pump is circulating

15A 250V F1

Fuse is

blown.

(See How to Replace the F1 15A 250V Fuse Section XI A).

Heater

elements

have failed

(See Heating Element Troubleshooting Section XII B).

Thermal

Cutoff switch

has been

tripped or

failed.

A resettable thermal cutoff switch located on the back wall of the

tank by the main power switch disables the heater element if the

temperature of the bath exceeds 90ºC. To reset the switch, allow the

temperature to drop below 80ºC and press the red reset button

between the wire terminals.

(See Thermal Cutoff Switch Troubleshooting Section XII C).

Temperature

sensor is

defective

(See Temperature Sensor Troubleshooting Section XII G).

7755 S Research Dr., Suite 105, Tempe, AZ 85284

Problem

Probable

Causes

What to Do

Flow in tank appears

less than normal

Flow from nozzle is

not uniform

White deposits

noticeable on dark-

colored parts

The cleaning

solution is

likely

saturated

with support

material.

Drain the tank and add fresh water and cleaning solution as

described in the User Manual. Generally, when the PH balance of

the bath reaches 11.5, the effectiveness of the dissolution drops

dramatically.

Type of

cleaning

agent.

If using Eco Works, try switching to Waterworks. Both are sold by

Stratasys resellers. Waterworks is a more efficient cleaning

concentrate.

Power cord gets very

hot

PEM is

defective

Older models may have PEMs with crimp issues. Contact support at

[email protected]m.

Power cord

is defective

or wrong

power cord

is being

used.

The 1200ht uses a power cord that is certified and rated specifically

for this model. Oryx does not advise using any 3rd party power cords.

Use of 3rd party power cords can result in damage to the SCA and

may invalidate any warranty. Please order any power cords directly

from Oryx.

III. Removing Top Cover and Back Panel

A. How to Remove the Top Cover

1. Remove the Top Cover

a) With the SCA unplugged, remove the plugs from the top cover.

b) Remove the six M5 screws holding the top cover.

Figure 1 - Removing Plugs and Screws
