MULTI-FUNCTION INDICATOR / PILOT LIGHT

Ultiscad's multi-function indicator / pilot light is designed as a solution to numerous needs in control panel indication and operator interface. It is a single-model product, with several user adjustable settings via DIP switches, to meet different application requirement. It reduces the quantity of indicators required on a control panel and facilitates noticing of abnormal equipment conditions because operators have fewer indicators to observe and anomalies are signaled with alternating or flashing lights (depending on user selected settings), drawing attention while giving precise and reliable visual notification.

FEATURES & ADVANTAGES:
1. 5 light colors (red, green, blue, amber, and white) and multiple functions for several applications are selectable via DIP switch.
2. Reduces inventory and ordering errors as a single-model product.
3. Suitable for narrow panel designs requiring lower congestion and space saving, one unit of MFI can replace three units of 2-wire indicators, reducing energy consumption and carbon footprint, while removing the need for push-to-test features in indicators. When separate 2-wire indicators are used, some of them will be off at certain times making critical operations to require push-to-test feature in indicators to verify that bulbs in off state are not burnt-out.
4. The 3 inputs of MFI are isolated (up to 2000V) and non-polarized, accepting a wide range of 48V to 125V AC and DC voltage. This allows for supplying different voltage types (AC or DC) of different levels (48V-125V) across them at the same time (The Superposition Theorem), should an application require that. The inputs can be wired to different circuits that are on separate fuse lines from same source. Each input is internally fused and protected from transients and spikes by metal oxide varistors (MOVs).
5. MFI is easy to install and configure, not requiring software or special skills.
Typical upgrades only involves moving wires to MFI terminals from multiple 2-wire indicators, setting required function in DIP switch, changing wire tags and replacing nameplates.
6. MFI's replaceable bulb has a lifespan of about 50,000 hours (5 years). Lighting is by combined effect of single diffused RGB LED bulb and outer dome lens (by LEDiL) for 340 degrees omnidirectional light, giving good visibility while reducing glare. MFI is built with high quality materials, designed to far outlive its bulb, and is sold with a limited 5 years warranty.
TYPICAL APPLICATIONS:
MFI is an innovative multi-function and multi-color indicator light for industrial control panels with numerous applications in switchgears, motor controllers, panelboards, mimic panels, chargers, UPS and redundancy systems, etc. Depending on desired application and DIP settings, MFI input terminals are logically monitored for presence or absence of voltage (48V-125V AC/DC) to indicate a light color, or lighting pattern.
Engineers and control systems designers, having studied MFI user manual can apply it to their designs based on possible indication options within the scope of its capabilities. Typical application of MFI are listed below, and further details are available in application notes and guides.
1. OPEN CIRCUIT INDICATION.
MFI-3 can be used to indicate an open circuit fault resulting from wire disconnection, broken fuse, etc. It is better, safer and more convenient for an open circuit fault to be indicated with a light color, rather than being represented by a light turned off, to distinguish it from a burnt-out bulb, without needing a push-to-test.
Four settings options are available including the following two:
1. Light is off in normal condition and red during open circuit fault (not recommended).
2. Light is white in normal condition and red during open circuit fault. This is recommended because it distinguishes between an open circuit fault and a burnt-out bulb.
2. BREAKER STATUS INDICATION (SWITCHGEARS, MOTOR CONTROLLERS, etc).
In this application, one unit of MFI can function like three separate 2-wire indicators of breaker status.
Typical usage includes:
1. Open, Closed and Maintenance Mode.
2. Open, Closed and Tripped/Locked Out.
Option 2 usually involves the use of NAC/NAT features of control switches to distinguish between an OPEN (breaker opened manually by use of control switch) and a TRIPPED (breaker tripped by a relay or locked out).
Over seven setting options are available based on user choice as shown in application notes and guides.
3. LOCKOUT RELAY STATUS INDICATION.
An important application of MFI is in lockout relays (LOR) status indication. Over six setting options are available with a recommended setting included in the application notes / guides.
MFI uses its open circuit indication feature, to signal a red light when the LOR or trip circuit is faulty. One unit of MFI functions like three separate 2-wire indicators of healthy, tripped and fault conditions.
In the recommended setting, MFI indicates a steady / continuous white light when LOR is closed and the trip circuit is healthy. When LOR trips, MFI verifies the health of the trip circuit with a white light, and every one second, it goes into a test mode to indicate a red light for one second. This shows its ability to indicate a red light when LOR or trip circuit fault occurs. The result is white and red alternating lights every second, signaling a tripped state. In this setting, MFI indicates a steady / continuous red light during a trip circuit or LOR fault, whether in a closed or tripped state.
Settings are also available (see application notes / guides) for most retrofits, where the users prefer the indicating pattern they are familiar with, especially LOR health-only indication in closed or tripped state.
4. UPS & REDUNDANCY SYSTEMS STATUS INDICATION.
one unit of MFI can be used to monitor outputs of 2 sources connected as a redundancy / backup system with a color such as green or white showing normal operation, while amber and red respectively show outage of one or both sources.
