Latch circuit is reset by disconnecting the supply voltage. Distributor’s ID No. Filled in by distributor when customizing the unit. Measuring voltage Coupling (set by DEIF) Supply voltage Type designation DEIF’s order ack. No. To be stated when contacting DEIF Highest voltage in relation to earth Installation category Special calibration (if non-standard calibration is applied) Scaling 1 (for adaption of the unit to the measuring power) Calibrated secondary power of the relay Mounted standard current module Relay coupling Shown is relay B as a normally de-energised relay, relay C as a normally energised relay with latch circuit 1. Description This protective overload relay type RMP-111D forms part of a complete DEIF series (the uni-line) of relays for protection and control of generators. 2. Label The relay is provided with a label with the following data: Note 1: Calculation of measuring power: ”X” x voltage module x current module x scale = measuring power ”X” is replaced by 2 for coupling 2W3 3 for couplings 1W3, 1W4, 3W3 and 3W4 Note: The relay is provided with a 200 ms power-up relay, ensuring correct function of the relay on connection of the auxiliary voltage. Normally energised contacts (”NE”) are not activated (contact does not open/close) until 200 ms after connection of the auxiliary voltage. Likewise, the relay is provided with a 200 ms power-down circuit, ensuring supervision and maintenance of any set point exceeding for 200 ms after disconnection of the auxiliary voltage. Installation and start up instructions RMP-111D 4189340123E (UK) 3. Mounting instructions The RMP-111D is designed for panel mounting, being mounted on a 35 mm DIN rail, or by means of two 4-mm screws. Weight: Approx. 0.650 kg The design of the relay makes mounting of it close to other uni-line units possible, however make sure there are min. 50 mm between the top and bottom of this relay and other relays/units. The DIN rail must always be placed horizontally when several relays are mounted on the same rail. 4. Connection diagram 2W3 3W3(4) A 2A fuse may protect all voltage inputs. The relay is protected against ESD (electrostatic electricity), and further special protection against this during the mounting of the relay is not necessary. Coupling Applied for measurement on 3W3 3 phase networks without neutral 3W4 3 phase networks with neutral If neutral is not accessible, the connection to terminal No. 16 (neutral) may be omitted without this affecting the accuracy of the relay, provided that the 3 phase voltages are identical.

No. 17 L3 to term. No. 19 L2 to term. No. 21 - connected to L2 (23 + 24), and to L3 (39 + 30) L2 to term. No. 17 L1 to term. No. 19 L3 to term. No. 21 5. Start up instructions 5.1 Setting and indication Setting of LED/relay Overload set point: (25…125%) of Pn ”P>” Yellow LED is lit when the set point has been exceeded, but the output contact has not yet been activated. Time delay: 0…20 s The contact is activated and the red LED is lit after the timer has expired. When setting the set points on the front of the RMP-111D an accuracy of ±5% of the scaling may normally be obtained. If a higher accuracy is required, the unit (the generator) connected to the relay must be loaded by means of a load bank. When the power exceeds the set point, the yellow LED of the RMP-111D is lit. 6.
