CLS52 Product Overview
The CLS52 is an intelligent display regulator widely used in industrial process control, supporting various thermocouples, thermal resistors, and standard signal inputs. It features high-precision measurement, dual output, and RS485 communication, suitable for display and regulation of parameters such as temperature, pressure, and liquid level.
This manual aims to help engineering technicians and procurement personnel quickly master the selection, installation, and commissioning methods of the CLS52.

Installation and Wiring
Installation Steps
- Confirm the instrument model and input signal type, and check the power supply voltage.
- Insert the CLS52 into the panel cutout (standard 1/8 DIN, cutout size 45×92mm).
- Fix it from behind the panel using the supplied clips to ensure the instrument is not loose.
- Connect the sensor, power supply, and output load according to the wiring diagram in the manual.
Wiring Precautions
- Thermocouple signals must use compensation wires, and pay attention to polarity.
- Thermal resistors are recommended to use three-wire connection to eliminate the effect of line resistance.
- RS485 communication lines should use shielded twisted pair, with the shield grounded at one end.
- Relay outputs must not directly drive high-power loads; an intermediate relay is required.
Parameter Settings and Commissioning
The CLS52 uses menu-based parameter settings, which can be completed via panel buttons. Long press the SET key for 3 seconds to enter the parameter menu, use the up and down keys to switch parameter items, and press the SET key to confirm and modify values.
Key parameters include: input type (InP), lower range limit (SL), upper range limit (SH), control mode (PID/ON-OFF), alarm values (AL1/AL2), and communication address (Addr). During commissioning, it is recommended to first set the input type and range, then tune the PID parameters.
Typical Application Scenarios
- Injection molding machine temperature control: With thermocouples and SSRs, achieve multi-stage heating of the barrel.
- Oven/baking oven: Dual outputs control heating and alarm respectively.
- Water treatment system: 4-20mA input displays liquid level or pressure, and RS485 uploads data.
- Laboratory equipment: High-precision measurement and transmission output to meet data recording needs.
Common Problems and Maintenance
Common Fault Troubleshooting
- Display shows "HH" or "LL": Input signal over range or sensor open circuit; check wiring and sensor.
- Measurement value fluctuates greatly: Check shield grounding, stay away from interference sources such as inverters.
- Communication failure: Check address, baud rate, and parity bit, and ensure A/B lines are not reversed.
Daily Maintenance Suggestions
- Regularly check whether the wiring terminals are loose and remove dust from the instrument surface.
- Perform accuracy calibration every 12 months, using a standard signal source.
- Avoid long-term use in humid or corrosive gas environments; install a protective box if necessary.
