Page 5: Before You Start
RMB. Before using the RMB, DEIF recommends reading the RMB Designer's handbook. The operator needs to know how to use the AGC before operating the RMB. To understand and operate the genset controllers, read AGC-4 Mk II documentation. -
Page 6: Check The Installation And Configuration
For a single genset without option T4, the controller is always in Semi mode during RMB operation. 2.6 Using multiple gensets Once installed and configured, operating an RMB with multiple gensets is just like operating the RMB with one genset. The first genset controller determines the set points for the other gensets. -
Page 7: Operating Procedure
Install the heavy duty service cables (to take over the load) from the genset(s) to the busbar or transformer. • Connect the RMB cables (data and voltage cables) from the RMB to the first genset’s RMB cable sockets. • In the first genset controller, in Genset Mode (parameter 6070) select Remote maintenance. -
Page 8: Start Generator
Check the phase sequence The phase sequence (rotation) must be checked, especially when connecting equipment to a new voltage source. To facilitate this check, a DEIF phase sequence relay, RMT-111Q96, can be installed in the switchboard. NOTE When all three phases are used to measure the voltage, the AGC automatically runs a phase sequence check. When measurement only uses one phase and neutral, the AGC cannot do a phase sequence check. -

4. The genset(s) run with a minimum of load while waiting for the next step. NOTE The minimum load is adjusted in parameter 7023. The default is 5% of the nominal power. RMB display unit LEDs Automatic Gen-set Controller Power... -
Page 10: Deload Mains
3.4 Deload mains Before After Load Load Mode: When the selector is turned to Deload mains, the mode in all controllers is changed to Semi. To deload the mains (load takeover): 1. In the first controller, adjust the power factor in parameters 7052 and 7053. 2. -
Page 11: Island
When the genset(s) are running in island, you can disconnect the Remote Maintenance Box without stopping the genset(s). Simply disconnect the RMB cables. The genset(s) continue running in island mode. When required again later, make sure that the function selector is on Island, then reconnect the RMB cables. Communication is restarted automatically. -
Page 12: Synchronisation To Mains
See the RMB Designer's handbook for more information. To synchronise to mains: 1. Connect your mains voltage measurement cables between the voltage mains banana sockets on the RMB and the mains connection point (fuses/breaker). See below for how to connect for 3-phase, or 1-phase measurements. - Page 13 Only one phase (L1) and neutral are connected on the Remote Maintenance Box. You must connect the neutral of the generator and the transformer correctly, so the common measurement point is the same. See the RMB Designer's handbook for more information.

Page 14: Deload Generator
3.7 Deload generator Before After Load Load Mode: Turning the function selector to Deload generator does not change the mode in the controller(s). The mains is now reconnected and the genset(s) can be deloaded: 1. Turn the function selector to Deload generator. 2. -
Page 15: Stop
The operator can stop the genset(s) by turning the function selector to Stop. After the cooling down time, the genset(s) stop automatically. The RMB, the RMB cables, and the heavy duty service cables can now be disconnected. All the equipment can be moved to the next maintenance job.
