Power Requirements
1. 115/230 VAC 50/60 Hz. Factory configured. ±10%
2. On 115V units, Alarm power is fused at the input with a 10-amp Time-Lag 5x20 glass fuse
[located on the main circuit board] (Pulsafeeder Part # 05-052-17) in line with the main
power cable.
On 230V units, Alarm power is fused at the input with a 5-amp Time-Lag 5x20 glass fuse
[located on the main circuit board] (Pulsafeeder Part # 05-053-18) in line with the main
power cable.
The Pumps are individually fused with a 12-amp Time-Lag ¼ x 1 ¼
(Pulsafeeder Part #05-051-79)
3. The power cable is 18 gauge, 3 wire, jacketed cable, 6 feet long.
DGF1 and DGF2 can be ordered without the power cable. This facilitates a hard wired
power connection. (Refer to Section 2 for wiring specifications / connections.)

Inputs
1. Liquid level wand for the glycol tank.
2. One or two pressure switch inputs depending on the number of closed loops in the system.
Pressure rating options are as follows:
a) Standard Pressure switch (10-80 psi)
b) Low Pressure switch (3-35 psi)
The standard pressure switch is open between 50 psi and 80 psi and closes at or below 30 psi.
All the inputs above are connected to the controller through a 6 conductor cable with a
Liquidtite on the enclosure.
A six pin locking header is on the circuit board side and 2 pin Molex connectors are on the
sensor side.
