13. unit is constructed with a PVC sensor pod and 3 stainless steel floats The support arms are stainless steel The floating sensor is supplied with 100ft of cable to the main 2852 controller If require more the supplied cable customer will require a weather proof splitter box and extra cable e g Beldon 8772 The main 2852 controller and any splitter box used should be mounted safely above the water surge level The PMC card which is potted within the float sensor translates the capacitance signal from the sensor into a frequency pulse which can then be transmitted up to one kilometer to the 2852 controller via 3 wire shielded cable The model is intended for use in General Purpose non hazardous areas For hazardous location use refer to Arjay Engineering Ltd For appropriate model 1 1 Features e Microprocessor based capacitance Controller e Relay and 4 20mA alarm output e Modbus protocol via RS 485 for access by Arjay handheld Central Access Panel or compatible system e Local Auto calibration or remote calibration via network e User specified custom features may be added by contacting Arjay Engineering Ltd 1 2 Model Number vs Voltage Input e 2852 HCF 1 100 240 VAC power input e 2852 HCF 3 12 VDC power input e 2852 HCF 4 24 VDC power input Model 2852 HCF User Manual Rev 1 3 1 3 Specifications Power Input 12 VDC 15 10 or 24 VDC 15 10 250mA maximum 100VAC 240VAC 10 50 60 Hz 150mA maximum
14. 2852 Controller Alarms The two relays on the 2852 HCF operate together The follow parameters are available as a common setting to the two relays 1 Delay Minimum time in seconds for an alarm to exist before the relays change to an alarm state The relay alarm state depends on the Relay Action and Failsafe settings The factory setting is 10 seconds to suppress false alarms due to sudden of intermittent flows or disturbances in front of the sensor 2 Action This determines if the Alarms LEDs should activate when the pF reading rises above or below the setpoint The factory default is below the setpoint because the application of water to oil is a decrease in capacitance 3 Failsafe Failsafe typically means that the relay is held in an energized state when in a normal operating condition as opposed to an alarm condition In an alarm condition the relay de energizes which is identical to when the instrument power is shut off The rationale is that the alarm condition should match the Power Fail condition The factory default is Yes for Failsafe 13 Model 2852 HCF User Manual Rev 1 3 4 3 2852 Controller Network The 2852 Controller may be monitored and calibrated via RS 485 protocol compatible digital communications Typical features are 1 Ease of wiring in multiple level point monitoring Up to 255 Model 2852 s or other Arjay 2800 Series level monitors may be connected together in a daisy chain 2 wire communication p
