RELAY CONTACT OUTPUTS
A set of relay contacts for high voltage (CR1) and fault (CR2) conditions is provided at TB2-3 and TB2-1 (Figure 4). One
end of these relay contacts are connected together and also connected to a source input terminal at TB2-2 (Figure 4).
When a source voltage is present at TB2-2 and either the high voltage is on or a fault condition occurs, the source volt-
age will become available at the output end of the corresponding contact. Maximum contact ratings are as follows:
MAXIMUM CONTACT RATINGS ( RESISTIVE LOADS)
DESCRIPTION DC AC
MAX SWITCHING CAPACITY 60 W 62.5VA
MAX OPERATING CAPACITY 30 VDC 125 VAC
MAX OPERATING CURRENT 2A .5A
When wiring to TB2, use a shielded cable and route the wiring through the standard I/O connector.
An internal 24VDC source voltage is available at TB2-4. Using a jumper wire, this voltage may be connected to TB2-2
to be used as the source voltage for the relay contact outputs. In this case, the total current sourced should not exceed
1-amp (Figure 3).
LOW VOLTAGE CABLE
Connect the low voltage cable from the control unit to the applicator using a wrench to tighten.
CAUTION
DO NOT over tighten the low voltage connection at the applicator.
The plastic parts could be damaged.
With the GMS design, multiple cables may be connected together to create the length required,
up to a maximum of 30m (100 ft.). To connect the cables, insert the male end of one cable into the female end of the
other. Tighten both cable connectors against each other using two (2) 16mm (5/8”) open-end wrenches.
