Product Details

HXK-1 programmable computer intelligent muffle furnace

Product Description of Programmable Computer Intelligent Muffle Furnace：

Appearance: The HXK-1 programmable computer intelligent muffle furnace adopts an integrated structure of upper furnace body and lower temperature control, with a novel and beautiful appearance. The furnace door is open and easy to operate. Due to the integration of the furnace body and control part, the cumbersome wiring connection between the two parts on site is avoided, making it easy to move and saving operating space.

Common fault causes and troubleshooting methods of programmable computer intelligent muffle furnace

Fault code	cause of failure	exclusion method
Err1	System failure	1. Not at zero, check IC4051 2. The proportional coefficient is not around 950. Check IC7650 and its surrounding circuits; 3. The ambient temperature shows below zero. Adjust the 101 potentiometer and check it LM134 (or 334)
Err2	Controllable silicon out of control	1. Thyristor breakdown, replace thyristor; 2. No trigger signal, check the trigger circuit;
Err3	Temperature display exceeds the range	This phenomenon is not a fault
Err4	Broken couple and temperature exceeding limit	1. Disconnect the thermocouple and replace it; 2. If the thermocouple compensation wire has poor contact or is disconnected, reconnect the thermocouple.
Err5	Temperature not sampled	1. Check IC4051; 2. Check IC7135.
