W-DIM4 RDM - RC4 Wireless

1. enters on the RED and BLACK terminals Each of the 4 dimmer outputs has a YELLOW and GRAY terminal for direct connection to load devices The W DIM4 will operate with input voltages from 6V to 30VDC It is important that the supply voltage does not drop below 6V while dimmers are driving their full load This can result in output flicker or oscillation the logic comes on activates the load the supply voltage drops under load the logic goes off the load is turned off the voltage rises the logic comes back on and so on Maximum non continuous output power for each dimmer channel is 180W Avoid short circuits which may damage the dimmer circuitry Ensure adequate ventilation around the W DIM4 to ensure dimmer heat can dissipate avoid blocking the ventilation slots on the side and top of the unit Prolonged operation at high temperatures can deform the case and damage the dimmer circuitry Duty cycle influences maximum power Given the ratings of the components a 250W load could be handled by one channel for a brief time But if a load is to be on for a significant period then a draw of 150W or less is recommended A fuse should always be installed at the battery terminals and in each individual dimmer circuit When operating all 4 dimmers with a 125W load at 12V the total current draw from the battery is 41 5A A 40A or 50A fuse should be used positioned as close to the battery terminals as possible A 15A fuse can be used on2. Manual W DIM4 Dimmer Test Mode Bump Buttons The button for each dimmer will momentarily turn the dimmer on at 75 while pressed The associated dimmer indicator Dim A D will come on along with the connected load Each dimmer indicator is immediately below the associated dimmer bump button Use these bump buttons and indicators to check wiring connections and lamps Dimmer bump buttons can be used to test dimmers and loads even when no transmitter is connected 12 RC4 LumenDim4 User Manual Assigning DMX Channel and Dimmer Curves Channel setup requires a W DMX or compatible transmitter and a DMX data source To assign DMX channels and dimmer curves using the hardware pushbuttons on the W DIM4 you must be able to bring up one DMX channel at a time to a specific level A portable Goddard DMXter Fleenor Gizmo BIC Pocket Console DMX or other similar device can be used if your regular console is inconvenient for this purpose You need two small pointer tools Bent paperclips are ideal Two recessed buttons must be pressed simultaneously to change a DMX channel assignment When you press the appropriate pair of buttons on the W DIM4 it determines the lowest channel that is currently on and what level it is at That channel can be assigned to any dimmer s and the level of the channel determines which dimmer curve will be used Here is the procedure 1 Zero all DMX channels 1 Bring up the level of a sin
