Troubleshooting Tytan Water Heaters

Tytan Water Heater

# Condition What to Check Action Required
1 General Heater Alarm/Heater will not engage/Main load contactor will not engage Future Design Overtemp limit controller 1. Verify that the thermocouple is in good working condition. Replace as needed. Consult the factory for the appropriate replacement component.
2. Verify that the controller is not locked into an alarm by performing a reset cycle on it.
3. Make sure the controller's alarm settings are appropriate for the current process.
Heater TCO 1. Locate the Heater TCO terminal connections, referencing the supplied electrical schematic. Using an ohmmeter, verify continuity through the TCO (less than 0.4 ohms). Replace as needed. Consult the factory for the appropriate replacement component.
SSR Heatsink TCO 1. Locate the SSR TCO, situated in the center of the heatsink, between the SSRs. Using an ohmmeter, verify the continuity through the TCO (less than 0.4 ohms). Replace as needed. Consult the factory for the appropriate replacement component.
2. Verify the operation of the fan located on the bottom of the heat sink. Replace as needed. Consult the factory for the appropriate replacement component.
OMRON Temperature controller alarm. 1. Verify that the thermocouple is in good working condition. Replace as needed. Consult the factory for the appropriate replacement component.
2. Make sure that the controller's alarm settings are appropriate for the current process.
Ground Fault alarm 1. Using an ohmmeter, measure each heater's power leads to earth ground and look for a shorted circuit. If a short to ground is identified within a column, it must be replaced. Consult the factory for the appropriate replacement component.
2. Check the flashing sequence of the LED light on the GFCI module. The flashing sequence will indicate whether there is an actual Ground Fault problem. The LED sequence can be verified against a label on the GFCI component. Replace as needed. Consult the factory for the appropriate replacement component.
Verify any customer interface connections that may apply. 1. Verify the customer interface is being used properly, per the electrical drawings that are supplied with your Tytan water heater.
2 TYTAN water heater will not power up Verify the incoming voltage is present on the TYTAN water heater. 1. Make sure that incoming facility voltage is active to the TYTAN water heater.
2. Verify it also meets the requirement of the water heater design. This requirement can be located on the identification label located on the front door of the TYTAN water heater.
Verify incoming power is on to the step down power supply and fusing located in the TYTAN water heater. 1. If Voltage is present on the incoming portion of the power supply, yet there is no output voltage, replace as needed. Consult the factory for the appropriate replacement component.
2. If the low voltage fusing is shown to have activated, replace as needed. Consult the factory for the appropriate replacement component.
3 Circuit Breaker will not engage Verify to see if the circuit breaker is in a tripped position and cannot be reset. 1. Try to reset the circuit breaker by turning the handle counter-clockwise, then attempt to turn the circuit breaker to the on position.
2. If it cannot be reset, check the Tytan's main power circuit for a direct short-circuit to ground. If no short- circuit is found, replace the circuit breaker as needed. Consult the factory for the appropriate replacement component.
4 Temperature Stability issues Temperature is over- shooting setpoint 1. Verify that the water flow has not turned off ,or that it is being reduced during normal process flow cycle.
2. Check the PID values in the OMRON controller. Perform auto-tune process as needed.
3. Check the settings in both controllers, and verify their output relays are not failed forward (in a permanently closed state).
4. Check that the SSRs are not failed forward (in a permanently closed state).
Tytan cannot reach setpoint 1. Verify that the flow has not increased from the normal process cycle levels.
2. Verify the heater fuses are operating properly. An activated fuse will not allow the full wattage capacity of the heaters to be used, and will reduce the performance of the TYTAN water heater. Replace as needed. Consult the factory for the appropriate replacement component.
5 Leak in the Column section of the cabinet Thermocouple fitting leak 1.Tighten the fitting to stop the leak, or replace as needed. Consult the factory for the appropriate replacement component.
Column manifold plumbing leak 1. Tighten up the sanitary flange connections. Inspect gasket seal for any damage. Replace as needed. Consult the factory for the appropriate replacement component.
Column is leaking 1. The column must be replaced. Consult the factory with the current serial number and model number to order a replacement column.
6 Display of the OMRON controller is showing an error message. (S.Err) Describes a thermocouple sensor error 1. Possible Thermocouple error problem. Replace as needed. Consult the factory for the appropriate replacement component.
7 Display on the Future Design overtemp device is showing an error message on the screen. (Senb) Describes a thermocouple sensor error 1. Possible Thermocouple error problem. Replace as needed. Consult the factory for the appropriate replacement component.
