How to fix 'Alarm: No SDU airflow' on DriSteem Control Systems?
If your DriSteem Control Systems unit displays 'Alarm: No SDU airflow', check the SDU for proper wiring, as the SDU blower or airflow proving switch may be incorrectly wired. Ensure the SDU blower cover is installed. If the SDU blower motor is inoperable (the SDU fan does not start), replace the SDU blower. Also, check if a breaker has tripped and reset it.
How to troubleshoot a VAPOR-LOGIC red indicator light that is off on DriSteem Control Systems?
If the VAPOR-LOGIC red indicator light is off on your DriSteem Control Systems, it could be due to several reasons: * First, check for proper supply voltage. * Second, inspect the heater fuses for voltage at the transformer. * Third, see if the transformer secondary circuit breaker has tripped; if so, check for wiring shorts and reset the breaker. * Finally, verify proper control cabinet wiring and try pressing the "RESET" button to reset the VAPOR-LOGIC control board in case of a microprocessor logic disruption.
Why can't I enter new parameters into the microprocessor through the keypad on DriSteem Vapor-Logic?
If you cannot enter new parameters into the microprocessor through the keypad on your DriSteem Control Systems, ensure that the digital display is not in "AUTO" or main menu format. Press the "MODE" key to enter the main menu, and then press the "ENT" key to access data in the selected main menu item. If new parameters are out of range, press the "CLR" key to start over and enter parameters within the acceptable range.
What does it mean when the VAPOR-LOGIC red indicator light is on continuously on DriSteem Control Systems?
If the VAPOR-LOGIC red indicator light is continuously on for DriSteem Control Systems, it may be due to a disruption in the VAPOR-LOGIC microprocessor. Verify proper control cabinet wiring and press the "RESET" button to reset the VAPOR-LOGIC control board.
What to do if there is no remote fault indication on DriSteem Vapor-Logic?
If there is no remote fault indication on your DriSteem Control Systems, there are a few things to check: 1. Ensure that field wiring is installed to a remote fault indicator from the VAPOR-LOGIC terminal block J7. 2. Check if the field-supplied remote fault indicator lamp is burned out and replace if necessary. 3. Verify relay continuity (VAPOR-LOGIC terminal J7) for contact closure, as the remote fault VAPOR-LOGIC relay may not be switching.
How to fix a DriSteem Control Systems read-out that is not auto scrolling?
If the read-out is not auto-scrolling on your DriSteem Control Systems, it might be because the digital display is in main or sub-menu format. Press the "MODE" key to return to auto scrolling.
Why is the DriSteem Control Systems display completely black?
A completely black display could be due to: * The keypad/display being overheated: Cool the keypad. * The communication cable not being connected: Connect the cable. * A defective cable: Replace the cable. * A defective keypad: Replace it. * A defective control board: Contact DriSteem.
What to do for DriSteem Control Systems 'Alarm: Tank overtemp'?
If your DriSteem Control Systems displays 'Alarm: Tank overtemp', it means the unit has overheated, with the temperature exceeding 25 ºF (14 ºC) over the boiling point. Check for proper water level in the tank. If the water level is adequate, the sensor may be faulty and require replacement.
What does 'Alarm: Tank temperature sensor failed' mean for DriSteem Vapor-Logic Control Systems?
If you see the alarm 'Alarm: Tank temperature sensor failed' on your DriSteem Control Systems, check the wiring terminals for correct wiring and voltages to ensure there isn't an open, shorted, or incorrect wiring issue with the sensor. For reference, 1000 Ohms corresponds to 68 °F (20 °C), and 1702 Ohms corresponds to 212 °F (100 °C). Also, verify that the humidifier interlock switches and/or over-temperature thermostat are wired correctly, that the interlock switch is set correctly, and that the humidifier cover is on; reset the over-temperature thermostat if it has tripped.
What to do if DriSteem Vapor-Logic Control Systems display is completely black?
If your DriSteem Control Systems display is completely black, first try cooling the keypad if it's overheated. If that doesn't work, check the communication cable to ensure it is properly connected. If the cable is connected, try replacing it as it may be defective. If the issue persists, the keypad itself may be defective and need replacement. If none of these steps resolve the problem, the control board may be defective, and you should contact DriSteem.
