Output relay chatters rapidly. Manual solution: Set P (proportional band) to a value greater than 0.5%. For ON/OFF control, set P = 0 and increase hysteresis ( Hyd ) to 2.0.
: Check whether your unit is rated for 110V AC or 220V AC . Applying 220V to a 110V unit will instantly destroy the internal transformer. Teqd-2301b Manual
: Indicates when the heating circuit is active. When lit, the internal relay is closed and sending power to the heating blocks. This light will cycle on and off as the unit maintains your setpoint temperature. Maintenance and Troubleshooting Common Faults and Solutions 1. The Controller Display / LEDs Do Not Turn On Output relay chatters rapidly
This controller is designed for high-heat industrial applications, offering a broad temperature range and a straightforward manual interface Technopack Corporation . It is often sold under brands like Hualian Machinery ГК Новые технологии Temperature Range: Power Supply: Available in both Technopack Corporation Control Interface: Features an analog rotary dial : Check whether your unit is rated for 110V AC or 220V AC
The TEQD-2301B is designed for temperature regulation on continuous band sealers. It is a direct fit and an essential component for models such as the:
| Terminal | Connection | |---|---| | 1 & 2 | Power supply (L & N) – 110V or 220V AC | | 3 & 4 | Relay output (to heating elements/heater) | | 5 & 6 | Thermocouple input (type E thermocouple) |
