OPERATING INSTRUCTIONS
The Remote Keypad Unit (RKU) is a portable, hand
held accessory for use with the York Variable Speed
Oil Pump Drive (VSOP). When connected to a VSOP
Drive it provides the ability to view the different con-
trols within the VSOP Drive. Typically, the RKU will
be used to determine what condition is causing the VSOP
Drive to fault. The RKU is powered by a 9 volt alkaline
battery (supplied). Auto Power-Down and backlight con-
trol features conserve battery life by automatically turn-
ing the RKU off after a specified time period and by
allowing selected use of the display backlight.
The Remote Keypad Unit has the abil-
ity to program many different controls
within the VSOP Drive. DO NOT
change any of these controls, they are
programmed at the factory and do not
require any adjustment. Problems as-
sociated with modifying any of these
controls WILL NOT be covered by war-
ranty.

INITIAL INSPECTION
Upon receipt, unpack and carefully inspect for any dam-
age sustained in transit (depression in the enclosure,
damage to parts, missing parts). If damage is apparent,
the shipping agent should be notified. If there are parts
missing, consult the Baltimore Parts Center.
The Remote Keypad Unit option consists of the follow-
ing components:
REMOTE KEYPAD UNIT SPECIAL PARAMETERS
The Remote Keypad Unit is an intelligent device con-
taining its own micro-computer, memory and special
parameters. Table 2 below lists these special param-
eters.
Ap Auto Power Down
This special parameter sets the length of time, in min-
utes, before the Remote Keypad Unit turns itself off if
no keys are pressed. If a data code of 0 is entered, the
Auto Power Down feature is disabled and the RKU
will remain on indefinitely. Figure 8 shows a typical dis-
play for this parameter.

PROGRAMMING THE SPECIAL PARAMETERS
To access these special parameters, press and hold the
PROGram
key for two seconds from either the opera-
tion or programming mode. After initial application of
power, the first parameter displayed will be AP - Auto
Power Down.
The parameter block area can be accessed while the
RKU is connected or disconnected from an VSOP
Drive. To program parameter AP - Auto Power Down
or bL - Backlight Control, use the following program-
ming method:
1. Press the
UP/DOWN
arrow keys to access the de-
sired parameter. The parameter number will be dis-
played in the upper left corner of the digital display.
2. Press the
SHIFT
key to allow the data code to be
changed. The
PRG
indicator will start to blink .
3. Press the
UP/DOWN
arrows to select the new data
code.
Note:
To automatically load the current default data
code, press and release both the
UP
and
DOWN
arrow keys simultaneously.
4. Press the
ENTER
key to store the new data code.
The display shows

for one second.
5. Press the
UP/DOWN
arrows to select a new pa-
rameter or press the
PROG
ram
key to return to
the operating mode.
LOW BATTERY POWER
The Remote Keypad Unit can be programmed to con-
serve power when operating from the 9 volt alkaline
battery (see parameters AP - Auto Power Down and
dL - Display Backlight). To protect the data and ensure
proper operation, the RKU will execute warning and
power conservation steps as outline in Table 4. Figure
11 shows the LCD display with the battery symbol ac-
tive indicating a low battery condition.

The fault codes range in value from 1-22. They are dis-
played in parameter 7, 8, & 9. The time since the fault is
displayed (in tenths of an hour) as the right most digit.
