Product Usage Instructions
Assembly and Mounting:
The ERC 213G should be mounted using the rear mount clip fixing
provided in the assembly. Refer to the drilling template for
accurate placement. The dimensions for mounting are specified as
36mm x 28mm x 71mm x 29mm x 83mm.
Wiring Diagram:
Refer to the wiring diagram for proper connections. Ensure that
the power connectors are torqued to a maximum of 0.4 Nm and signal
connectors to a maximum of 0.2 Nm.
User Interface and Button Functions:
The user interface includes buttons for Drain, Hot gas, and Sair
functions. Follow the button functions listed in the manual for
various operations such as RESET, BACK, TEMPERATURE SETPOINT
adjustment, MENU access, and ON/OFF control.
Menu Structure:
The menu structure allows access to parameters, settings, and
service options. Use the SET button for state adjustments, sensor
type selection, setpoint temperature changes, and alarm code
viewing.
Safety Standards:
Prior to installation, ensure correct input voltage. Avoid
exposing the controller to water or damp conditions. Operate within
design limits to prevent condensation due to sudden temperature
changes with high humidity.
Product Disposal:
Dispose of the device in compliance with local waste disposal
regulations to ensure proper environmental handling.
FAQ
Q: What is the purpose of the ERC 213G?
A: The ERC 213G is designed for air-dryer applications to remove
moisture from compressed air.
Q: How should I adjust the setpoint temperature?
A: Use the SET button to adjust the setpoint temperature and
UP/DOWN buttons to change the temperature value. The setpoint will
flash in setting mode.
Q: What should I do in case of an active alarm?
A: View the active alarm by pressing the SET button. The
temperature setpoint must be saved to resolve the alarm
indication.
