ECHOTEL® 961/962 Ultrasonic level switches DESCRIPTION The Echotel® 961/962 series utilizes pulse signal technology to detect high or low level alarm(s) in a broad range of viscous to light liquids. Pulsed signal technology provides superior performance in applications suffering from foam, aeration, heavy turbulence and suspendid solids. The Echotel® 961 has a tip sensitive setpoint and is ideally used as high or low level alarm. The Echotel® 962 offers 2 setpoints on the same transducer, a tip sensitive setpoint and a second setpoint via a flowthrough upper gap. The unit is used for level alarm or to control a pump in an auto fill/empty mode. The Echotel® 961/962 is equipped with advanced diagnostics that continuously check the transducer and electronics. The diagnostics also alarm for electrical noise interference from external sources.

The signal is then converted into ultrasonic energy and transmitted across the sensing gap towards the receiver crystal. When there is air Loop Power in the gap, the high frequency ultrasonic energy will be attenuated, thereby not allowing the energy to be received. When there is liquid in the gap, the ultrasonic energy will propagate across the gap and the current shift or relay output will indicate a reception of the signal. mA 21 16 12 8 3,6 Safe Alarm (962 only) Alarm Normal Operation Selectable Fault Signal Error Air/Gas Dry gap Liquid Wet gap MOUNTING Ambient temperature: -40°C (-40°F) to +70°C (+160°F) High alarm High high alarm Filling line Pump control High alarm High alarm Auto fill or empty pump control Pump protection Low alarm Pump A P P L I C AT I O N S Fill Line High Alarm Dual Point Alarm Pump Protection Low Alarm High/Low Level Alarm 2 Pump Control E L E C T R O N I C S S P E C I F I C AT I O N S Description Input Voltage mA - version Relay - version Power Consumption Output Time delay Indication Selftest Housing material mA - version Relay - version Automatic Manual Approvals SIL (Safety Integrity Level) Electrical data Equivalent data Shock/Vibration Net weight PERFORMANCE Description Response time Repeatability Ambient Temperature Humidity Electromagnetic Compatibility Specification 2 wire loop powered, 11 - 35 V DC 102 - 265 V AC 50/60 Hz or 18 - 32 V DC < 3 Watt (relay version) – < 1 Watt (mA version) 961: 8 mA (safe), 16 mA (alarm) ± 1 mA 962: 8 mA (safe), 12 mA (lower gap alarm), 16 mA (upper gap alarm) ± 1 mA 961/962: ≤ 3,6 or ≥ 22 mA error signal 961: one 5 A DPDT relay 962: two 5 A SPDT relays 961/962: one 5 A SPDT malfunction relay 0,5 to 45 s adjustable (in addition to transducer response time) LED’s for process alarm status, malfunction (error of transducer, electronics or electrical noise interference) and wet/dry status of transducer (961 with relay only) Continuously verifies electronics, transducer and noise interference Via pushbutton for checking alarm output(s) and error output/function IP66, cast aluminium or cast stainless steel ATEX II 1 G Ex ia IIC T5 Ga, intrinsically safe (current shift units with metal transducers) ATEX II 1/2 G Ex d IIC T6 Ga/Gb, flameproof enclosure (units with metal transducers) IEC Ex d IIC T6 Ga/Gb Overfill prevention TÜV - WHG § 19 / VLAREM II 5.17.7 Other approvals are available, consult factory for more details Functional safety to SIL 2 in accordance to IEC 61508 – SFF > 90 % Full FMEDA report and declaration sheets available at request Ui = 28,4 V, li = 94 mA, Pi = 0,67 W (mA version) Ci = 10,4 nF (961) / Ci = 60 nF (962), Li = 400 µH (mA version) ANSI/ISA-S71.03 Class SA1 (shock), ANSI/ISA-S71.03 Class VC2 (vibration) Alu: 1 kg (2.2 lbs) – electronics only SST: 2,5 kg (5.5 lbs) – electronics only Specification 0,5 s typical ± 2 mm (0.078") -40 °C to +70 °C (-40 °F to +160 °F) 0-99 %, non-condensing Meets CE requirements (EN 61326: 1997 + A1 + A2) and NAMUR NE 21 T R A N S D U C E R S P E C I F I C AT I O N S Description Plastic transducers Mounting Threaded (NPT/BSP) – Flanged (ANSI - EN (DIN)) Material Actuation length Process temp.

In applications with turbulent or boiling surfaces, this may lead to scattering of the output. For these applications, the user can adjust via a potentiometer a time delay from 1 to 45 s and avoid scatter of the output. Fault LED reports a malfunction of the unit. The blinking sequence of the LED identifies the failure (electronics, transducer or electrical noise interference). Malfunction LED (only for units with relay) confirms that the malfunction relay is energized in normal operation FUNCTIONS Pushbuttons for manual check: The alarm output and the error signal of the Echotel® 961/962 can be manually checked via pushbuttons. For loop powered units, the loop test pushbutton will sequentially check the shift of loop current. For relay operated units, the level test pushbutton will make the relay change from energized to de-energized status or vice versa. Pressing the fault/malfunction pushbutton stops all transmit pulses, which simulates an electronics failure, and tests the selected output signal. LED identification: Alarm LEDS report alarm status. For 962 models, the alarm status per gap is reported. A separate LED on the 961 model (with relay output), reports independently from the alarm status, whether the gap is immersed or not. Pump Control (only 962 model with relays): The model 962 with relays can be set for pump control or level alarm. By selecting pump control (PC), the unit will latch its 2 SPDT relays and provide automatic fill or drain function between its 2 setpoints. In level alarm mode (LC), the unit will detect either high and high-high or low and lowlow level alarm. Selectable error signal: The error signal of loop powered units (961/962) can be set for either 3,6 or 22 mA. The separate malfunction relay of the 961 can be set for independent or joint operation with the alarm relay. The 962 with relays will always report a malfunction via the alarm relay.
