Section 2c: Output Power Guidelines
TOTAL
current draw from the U30 Microprocessor Control must not exceed 350 mA (0.35 amps)
when outputting power to:
►
►
Sensors
►
►
Modules
►
►
Accessories
►
►
Auxiliary Equipment
If
TOTAL
current draw exceeds 350mA (0.35 amps) the installer must utilize an auxiliary power
supply such as a 24 VAC Transformer (P/N 14-2101).
The U30 Microprocessor Control and/or the NABCO Power Supply Module Must
Not be used to output power to Magnetic Locks or Electric Strikes.
To determine if an auxiliary power supply must be used, add together each current draw for each
device. Please refer to the formula shown below:
Example: A GT-1175 Slide Door is to be fitted with the following devices:
2 x Optex i-one Sensors @ 130 mA = 260 mA
1 x Optex Beam Module @ 160 mA = 160 mA
Total = 420 mA
420mA exceeds 350mA. An Auxiliary Power Supply must be used to supply
power to the Optex Beam Module.
Section 2d: Header Layout
Nabco GT-1175 Sliding Door systems come in many sizes and configurations. Because of this
components within the Header are layed out in (1 of 3) different configurations to ensure proper
operation of the Drive Belt. Please see configuration details listed below:
►
►
Operator/Control/Power
•
Header Width is not wide. Operator needs to be installed to the left of the U30
Microprocessor Control. Please see
Figure 2-1
.
►
►
Power/Operator/Control
•
Header Width is wide, but Operator still needs to be installed between the Power Supply
and the U30 Microprocessor Control. Please see
Figure 2-2
.
►
►
Power/Control/Operator
•
Header Width is wider. Operator can be installed to the right of the Power Supply and
the U30 Microprocessor Control. Please see
Figure 2-3
.
Note: The Power Supply must never be installed between the U30 Microprocessor Control and the Operator.
Note: No matter the location, electrical wiring for all (3) components stays the same.
