Introduction
The Raypak Y-200 Series Controller, equipped with
the Y-305 4-20 mA / 2-10 VDC Module, provides the
ultimate in temperature setpoint control for Raypak
boiler applications. The Y-305 4-20 mA / 2-10 VDC
Module provides a conversion, from either a milliamp
or a voltage input from an outside control source, to a
setpoint temperature reading on the Y-200 series controller LCD panel.
The Module is provided in a kit which includes the necessary hardware to install the board onto the Y-200
control board. This manual should be used in conjunction with the Y-200 Series Installation & Operating
Manual (Catalog No. 5000.62, P/N 241125).
Important Safety
Instructions
IMPORTANT NOTICE: These instructions are
intended for use by qualified personnel who are
specifically trained and experienced in the installation of this type of equipment and related system
components. Some states may require that installation and service personnel be licensed. Only qualified persons shall attempt to repair this equipment.
Repair must be done according to the instructions
provided.
WARNING: Improper installation, adjustment,
alteration, service or maintenance may damage the
equipment, create a hazard resulting in asphyxiation, explosion, fire, electric shock, personal injury or
property damage, and void the warranty.
CAUTION: This appliance has provisions to be
connected to more than one (1) supply source. To
reduce the risk of electric shock, disconnect all connections before servicing.
CAUTION: Risk of electric shock: More than one
(1) disconnect switch may be required to de-energize the equipment before servicing.
NOTE: Minimum 18 AWG, 105°C, stranded wire
must be used for all low voltage (less than 30 volts)
external connections to the unit. Solid conductors
should not be used because they can cause excessive tension on contact points. Install conduit as
appropriate. All high voltage wires must be the same
size (105°C, stranded wire) as the ones on the unit
or larger.
Installation
1. Verify that the control signal is within the 4-20 mA
/ 2-10 VDC parameter.
2. Turn off the power to the Y-200.
3. Open the front cover of the Y-200 to access the
display/keypad door.
4. Open the display/keypad door to access the Y-200
Control Board (P/N 601670).
5. Secure the nylon standoff (P/N 550767) onto the
Y-200 Control Board as shown in Fig. 1.
6. Plug the Y-305 4-20 mA / 2-10 VDC Module into
the Y-200 Control Board at the J20 expansion port
(10-pin plug), securing Module with nylon standoff.
7. Attach 4-20 mA / 2-10 VDC signal wires to 2-pin
plug connector (P/N 650935).
8. Plug 2-pin connector into either the J1 or J2 connection of Module (J1 for 4-20 mA operation, J2 for
2-10 VDC operation).
