SAFETY CONSIDERATIONS

Installation of this accessory can be hazardous due to sys-
tem pressures, electrical components, and equipment location
(such as a roof or elevated structure).
Only trained, qualified installers and service technicians
should install, start up, and service this equipment.
When installing this accessory, observe precautions in the
literature, labels attached to the equipment, and any other
safety precautions that apply.
• Follow all safety codes.
• Wear safety glasses and work gloves.
• Use care in handling and installing this accessory.
WARNING
Electrical shock can cause personal injury and death. Shut
off all power to this equipment during installation. There
may be more than one disconnect switch. Tag all discon-
nect locations to alert others not to restore power until work
is completed.

GENERAL

The standard Touch Pilot
all 30XV chillers is programmed to accept various options to
modify the unit operation. The Energy Management Module
(EMM) board is required for 4 to 20 mA, 2 or 3-step demand
limit control, chilled water temperature reset by space tempera-
ture or 4 to 20 mA, and Ice Mode. Chilled water temperature
reset by return water or cooler delta T does not require the addi-
tion of this accessory. See Table 1 for EMM functions. The fol-
lowing functions are available with the EMM board:
• Chilled Water Temperature Reset - Resets the chilled
water set point under less than full load capacity condi-
tions by the following methods:
4 to 20 mA Input: A field-supplied signal generator
-
and 1 / -watt, 250-ohm resistor are required.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

• Demand Limit - Limits the capacity of the machine from
unit capacity by the following methods:
4 to 20 mA Input: A field-supplied signal generator
-
and 1 / -watt, 250-ohm resistor are required.
2
2 or 3-Step Switch Control: A field-supplied dry con-
-
tact switch is required (One-Step Demand Limit does
not require the EMM board).
• Occupancy Override - Extends the occupied period for
machine operation. A field-supplied dry contact switch is
required.
• Remote Chiller Lockout - Disables the chiller when
closed. A field-supplied dry contact switch is required.
• Ice Done Control Switch - Signals the machine to exit
the Ice Build mode and enter an unoccupied time period.
A field-supplied dry contact switch is required.
The following status functions are available with the EMM
board:
• Capacity Output Signal - A 0 to10 vdc analog output
signal indicating chiller capacity is available.
• Shutdown Status Relay - A 24 vac output signal indi-
cating that the machine is shutting down.
• Alert Relay - A 24 vac output signal indicating the unit
has an active alert.
• Compressor Run Status - A 24 vac output signal (one
for compressor A, one for compressor B), indicating the
compressor is on.
The EMM board can be configured with the Touch Pilot
module.
