Frequently Asked Questions
Q1: What four basic parameters are required during the quick start-up procedure?
A1: Initial configuration requires selecting the refrigerant type, valve control mode, pressure probe type, and application type (such as chiller, walk-in cooler, or display case). When paired with CAREL valves, only three parameters are needed.
Q2: Can pressure transducer signals be shared between multiple EVD0000E50 drivers?
A2: Yes, the driver supports 4 to 20 mA low-power ratiometric pressure transducers whose output signals can be shared across multiple EVD controllers to optimize installation costs.
Q3: How does the parameter cloning function simplify multi-circuit system commissioning?
A3: Using the removable graphic LCD interface, operators can save complete parameter profiles from one configured EVD driver and download them directly into other EVD units across the system.
Q4: What standard warranty applies to Ruifujie electronic control modules and drivers?
A4: All electronic controllers, drivers, and valves supplied across our catalog are backed by a standard 1-year comprehensive warranty.
Q5: What payment methods and trade terms are supported for commercial export orders?
A5: We accept T/T (Telegraphic Transfer) and Western Union, with standard export shipments executed under FOB Shenzhen or EXW terms in USD.
