2 functional description the HPR is voltage level controlled. this means, it will be programmed ex-factory how it should work: either like a signal-controlled relay, practically as a monostable function, or with an impulse like a bistable relay and even with a defined voltage level. delay times (t on or t off ) can be programmed in the microcontroller. the relay will then be switched on or off after a defined time. measurement of the input signal is analog. this allows checking the system voltage. so for instance if the battery voltage falls below a certain programmed level (e.g. 5 v), the relay can open the main contact (automatic load shed). as soon as the level rises again (e.g. > 16 v) it will be switched back on. activation: there are two ways of activating the relay: level or pulse. the level activation requires a high signal being applied to the in+ terminal so that the relay switches on the load. the low signal disconnects the load. with the pulse activation the relay alternately switches the load on and off with each pulse. filter function in the activation: this function serves for tolerating disturbances on the activation line. incidental peaks or contact chattering will then not cause inadvertent connection/disconnection of the load. the value configured for this function determines how long a control signal has to be applied permanently to the control input until it will be recognised as such. should there be dips in the control signal during the configured time, it will not be recognised as activation. information: inadvertent activation can thus be prevented. low voltage detection: this function serves for undervoltage protection. if the volt - age applied to the relay falls below the pre-set value (u off ), the load will be disconnected. if the voltage rises again, the relay can be switched on again either automatically at the preset value u on or otherwise the switch-on procedure has to be re-triggered. this would for instance prevent inadvertent start-up of a machine as requested by the current machinery directive. low voltage detection is via internal tap (sense) at load contact 88. behaviour in the event of reset of the operating voltage will be configured. automatic on or off caution: if e.g. an extreme discharge of the battery has the system voltage fall very quickly below the critical value, the electronic circuitry does not have enough time and energy to energize the relay. we rec - ommend to set the status to a safe condition as soon as the operating voltage is restored, i.e. to the off condition. iaio 16 level activation with filter function pulse activation with filter function in t filter t filter t filter t filter t filter in load load level activation pulse activation in in load load low voltage detection u b u on u off load www.e-t-a.de hybrid power relay (HPR) 1630 5
3 configurator a programme for configuring the HPR10 is available on the e-t-a website. it allows selection of various functions and sets up the corresponding ordering code. http://relaisconfigurator.e-t-a.com/light/de/ schematic diagram HPR ybrid (wi eleroi orol i) 30 on/off switching delay the relay features a timer function allowing delayed switch on or off of the load, e.g. for applications with exhaust aftertreatment (scrt catalytic converters). this function allows delayed switch-on of the relay. the configured value indicates the time elapsing between activation and switch-on. information: thus the relay may for instance give time to other system components to carry out their start-up, probably attenuating the inrush current peak in the entire system. this function allows delayed switch-off of the relay. the configured value indicates the time elapsing between activation and switch-off. information: an overrun is desired in many applications, e.g. to give some orientation with illuminations even after switch-off or to give a load enough time to complete the switch-off process. off delay (over run time) in t off t off load on delay in t on t on load www.e-t-a.de hybrid power relay (HPR) 1630 5 hybrid power relay (HPR)
