Mounting the control
The CL-6 regulator control from Eaton can be mounted
on the regulator tank or at a point remote from the unit.
Rubber-covered cable is available for interconnection
between the control and the regulator. Refer to the
Accessories section of this manual.
Placing the control into service
Refer to the appropriate regulator manual, as indicated on
the regulator nameplate, for specific information on the
regulator installation (see Figure 3-3). Refer to Tables 2-1
and 2-2 for control specifications and metering accuracy.
When energizing the control from an external source, use
only a 120 Vac source, unless the control was configured
for 240 Vac, as indicated by a decal adjacent to the
terminals.

Setting the control for service
The control must be properly programmed for service. Refer
to the Initial Control Programming section of this manual.
The control must be energized to be programmed. Apply
120 Vac, or other voltage as indicated by decal, to the
external source terminals; ensure the ground wire is
connected to the ground terminal; and place power switch
in the external position. Alternately, the regulator may be
energized at line potential and the power switch placed in
the Internal position.
When power is applied to the control, the self-diagnostic
routine will commence and the LCD display will activate,
followed by a PAS S message. Check the date and time
displayed and reset if necessary. If the FAILURE or
Diagnostic Error message is displayed, refer to the
Troubleshooting section of this manual.
Section 2: Control installation
WARNING
Hazardous Voltage. To protect personnel from surges
while operating the control, follow these control
enclosure grounding procedures: a) If the enclosure is
attached to the regulator tank or is remote from the
tank but only accessible with a ladder, connect the
enclosure to the regulator-to-ground rod conductor; b)
If the enclosure is accessible by personnel standing on
the ground, connect the enclosure directly to a ground
mat and ground rod. Failure to comply can result in
severe personal injury or death.
WARNING
Hazardous Voltage. The control box must be solidly
earth grounded. Failure to comply can cause severe
personal injury and equipment damage.
CAUTION
Equipment damage. Only an ac power supply is to be
used to energize the control externally. Do not use a
dc-to-ac voltage inverter. Failure to comply can cause
excessive harmonics to be generated and result in
damage to the front panel.
CAUTION
Equipment damage. Be mindful of polarity when using
an external source. Polarity reversal will result in control
damage.
