PUSH BUTTONS AND OPERATOR
INTERFACE
[105] When ordering, add prefix 9001 to the catalog number.
[106] ▲ Add the voltage assembly code as chosen from Standard and Shallow Depth Light Modules, page 19-91.EXAMPLE: SKT•••R31 with 208 Vac red LED voltage = SKT37LRR31.
[107] ■ Add the color code as chosen from the color cap table below.EXAMPLE: SKP1 with a blue fresnel cap = SKP1L31.
[108] The cap must be the same color as the LED light module chosen, e.g., for a green LED, use a green color cap.
[109] On neon light modules, use clear color caps only.
[110] Use only full voltage or resistor voltage assembly codes on remote test pilot lights. Do not choose LED, neon or transformer codes. For AC use only.
[111] Use only full voltage or resistor voltage assembly codes on remote test pilot lights. Do not choose LED (exception — these LED codes are allowed: 38LG, 38LL, 38LR, 38LW, 38LY), neon or
transformer codes. For AC use only.
[112] Add the color code as chosen from the color cap table below.EXAMPLE: SKP1 with a blue fresnel cap = SKP1L31.
