3. MOUNTING AND WIRING

3.1 Prepare a 3.58 x 3.58" ±0.02" (91.0 x 91.0mm ±
0.5mm) panel cutout (refer to Fig.2). The panel
on which the controller will be mounted may be
up to 0.4" (10mm) thick.
3.2 Slide the meter into panel through the cutout.
3.3 Affix the mounting brackets to the top and
bottom of the meter and tighten the bracket
screws. Do not tighten the screws excessively.
3.4 Connect the power cord to the meter but do not
connect to power source.
3.5 Connect sensor input and control/alarm outputs.
3.6 Connect power to source.
Wiring Notes:
AC: The AC supply terminals can
handle 85 to 260VAC 50/60Hz.
Control Output Relays: Terminals
14,15 and 16,17 (NO); Terminals
16,18 (NC).
Alarm Relays: Terminals 11, 12 and
12, 13 are N.O. when controller is
powered down
powered-up in non-alarm condition.
2-Wire RTD Inputs: Connect RTD
across terminals 9 and 10. Short
terminals 8 and 9.
4-Wire RTD Inputs: Connect in the
same fashion as a 3-wire and leave
the 4th RTD wire open.
24VDC Pulse Output option: Use the
same terminals and polarity as 4-20mA outputs (shown in Figure 3).
Warning: An independent redundant alarm should be used if control/alarm relay failure
could result in potential harm or damage.
