. 16.... 15.3 General characteristics the signalling relays The following data are defined for resistive loads (cos 1) Type contact SPST Maximum switching voltage 130 VDC 380 VAC Maximum switching current A Maximum switching power 175 2000 VA Breaking capacity VDC .1.5 PR021/K signalling unit menu The unit's functions are accessible from the operator panel (PR123/P and PR122/P where applicable) M 4/4 Enter PWD L Bus 1/8 Enter J R n.1. The function entirely similar the one described the PR120/K signalling module par. These contacts enable various applications, including load control, alarms, signals, electric cutouts..1. A Breaking capacity 380 VAC .2 Power supply Auxiliary power supply +/-20% Maximum ripple 5% Rated power 4... 5.5 this manual. Breaking capacity 120 VDC 0.Appendices 16.. Two contacts available the SACE PR021/K (load control) unit enable you control arelease for opening and closing the circuit-breaker. Information the status the protection functions transits dedicated serial line connected the release.3 and 16. By setting the DIP switches, you can configure the signals programmable contacts, This can done selecting them directly the PR121 relay via PR010/T, SD-Testbus SD-Pocket; PR122/P PR123/P relay, choosing from long list, including: directional protection trip minimum and maximum voltage trip and OV, reverse power trip and others.1 eneral inform ation The signalling unit converts the digital signals provided the protection units into electrical signals means normally-open electric contacts.1 llin it 16.2 A Contact/coil insulation 4000 Veff Contact/contact insulation 1000 Veff 16..N°.2 . 125/158 .1 1/4 C A S le 1 1 R n. A Reset button enables you zero the status all the front optical signals and return the relays' contacts the resting position.1.4 W 16. 16. Breaking capacity 250 VAC .1 R n. 2 Page No.2 D y N ▼---------------W Unit configuration Present None Model L2234 Apparatus Scale L2778 Doc..1.. The unit also contains ten LEDs display the following information: - Power ON: auxiliary power supply on - Tx(int Bus): flashing synchronized with dialogue with the Internal Bus - Eight LEDs associated with the signaling contacts. The following signals/contacts are available: - overload prealarm (the alarm signal remains enabled throughout the overload, until the release has been tripped) - protections timing and trip (the protections trip signal remains enabled during the timing-controlled phase and after the release has been tripped) - protection trip - timing and overheating threshold overrun - two contacts for load control - release trip - communication error serial line (connections between protection and signalling units) - phase unbalance..4 Relay functions The available contacts can used manage the respective relays indicating event given situation the state the device) that prompts the required relays independently enabled after the delay specified the user
