5.3.4 INTELLIGENT BLACKOUT TIME DELAY (self-learning models only)
The JEA also has an Intelligent Blackout delay, meaning depending on the disconnection period, caused by no power i.e. power
cut or mains being turned off, the JEA will adjust the wait period before allowing the compressor and other outputs to turn
on. For example, if the Time delay is set to 3 minutes, a 2-minute disconnection will result in only a 1-minute additional delay,
making the total delay 3 minutes. Any disconnection of 3 minutes or over and the JEA will immediately turn the compressor ON.
Time delay is configurable (intelligent time delay and blackout time delay is set as the same value).

5.4 PRODUCT SAFETY FEATURES
5.4.1 DOOR LOCK
The JEA can control a door lock system via a Modbus interface. This feature prevents coolers from being opened when stores
are closed, or contents could be compromised to prevent theft/sale of defective food or drinks.
Currently, the door lock is set to “normally locked”. This means the door is locked and when triggered the door is unlocked for
10s. Normally unlocked settings can be implemented if required.
5.4.2 LOCK OUT MODE
The JEA will enter cooler lockout mode if the regulating temperature is above a customer-defined temperature (LtP)
continuously for a settable duration (LDr). In this mode, all relays are OFF and flagged as an alarm via the display (Loc for
models with a display or the red and green LED flashing for models without a display). The JEA will remain in lock-out mode
even if the power is cut, the only way to exit lockout mode is via manual intervention by sending a special command (either via
Modbus or the GUI) to the JEA. By forcing manual intervention, the operative while resetting the JEA can also ensure foods and
drinks have not perished during prolonged overtemperature and remove anything that has to ensure customers receive quality,
fresh products.
Once the lockout is released, the cooler starts operating normally in Initial Pull Down mode. Next lockout can happen only after
the temperature inside the cooler reaches cut-out temperature (pull down is over).
5.5 CONNECTIVITY SOLUTION (if fitted)
Connectivity devices are fitted to the 8-way data connector at the rear of the JEA. Refer to the Section 3. Installation for more
details on how to do this.
5.5.1 BLUETOOTH
JEA controllers are equipped with Bluetooth capability, enabling them to connect to the Sollatek Smart device Application. The
Sollatek App has extensive cooler management capabilities. The JEA controller also features iBeacon and Eddystone Beacon
capabilities allowing proximity marketing to send engaging and interactive content to consumers’ smartphones while they buy
in real-time. There are several options to equip the JEA with BLE:
• JEA with internal built-in BLE
• FFX Expander port with built-in BLE plugged into the JEA
• Connectivity device with BLE plugged into the JEA
