All technical personnel should review the "Safety Protocols" section prior to first use. A copy of the manual should be retained in the control cabinet documentation folder for future maintenance reference.
Before diving into the manual, it’s crucial to understand what the Brj-502 is and isn’t. The Brj-502 is a DIN-rail mounted, 24V DC-powered control unit with:
The Brj-502 supports two programming methods:
To prevent false alarms and structural sensor damage, install the BRJ-502 in the following zones: Directly above a high-heat cooking surface or stove. Outdoors or in areas exposed to heavy weather elements. Brj-502 Manual
Sets system to Heat (reverse action) or Cool (direct action). Alarm 1 Value User defined Triggers auxiliary relay at designated limit. Hy Hysteresis 0.1 – 50.0 Sets the ON/OFF deadband when not using PID. LCK Parameter Lock 0000, 0001, etc. Prevents unauthorized tampering with deeper settings. How to Run Auto-Tuning (AT)
